These civil engineers must play a lot of cities skylines Also RIP my Raleigh interchange video idea you will be missed

My pick is i-78 at Newark Intl. Airport. It's the convergence of a massive expressway, three minor expressways, a massive toll road, an airport, and a major port.

Another crazy interstate crossing/interchanges are in Nashville, TN (downtown). If you are traveling on I40 (either direction) you have exits for I65, I24, I440, which causes so much confusion - especially going downtown.

A fun one is Wis-29, WI-32, and I-41 in Green Bay. In trying to make nice ramps to go freeway to freeway they made staying on East WI-29 and go downtown an absolute nightmare. Get off at the exit before, go around a roundabout, under the freeway, another roundabout, follow the freeway on a surface street for a half mile, then four more roundabouts for ramps and arrive roads for I-41, then finally on to Shawano Ave and heading to Downtown. The worst part is this is new, this isn’t some relic of the 1960’s this was built in the 2010’s

The 24/40/65 loops in Nashville belong on this list. And just for the massive size of it, the Springfield Interchange (95/395/495) in NoVa also belongs on this list

Beaver, loved this video!! Here are some ideas to include for the next vid on this topic: - I-78, US 1&9, NJ 21, and the NJTPK at Newark airport. This is a series of spaghetti interchanges that will makes your head spin. - I-76, i-80, and the Ohio turnpike near Youngstown OH, not because of the design but because it’s interesting how 80 and 76 switch carriageways here - i-76, I-295, and NJ 42 just south of Philly in its NJ suburbs. This interchange has been under construction for a minute and is probably the biggest bottleneck in south Jersey. - I-84 and I-91 in Hartford CT. Honestly, you could make a video about how terrible Connecticut’s left exits are in general. - I-93 and I-95 just north of Boston, Mass. this is a simple cloverleaf design where the two busiest highways in the Boston area meet. Weaving and outdated single lane ramps create terrible traffic, SMH MassDOT

In Interchange Design, it's really not only about the interchange looking good, but rather about getting traffic to flow well. For example this Interchange in Birmingham you've mentioned, it may look confusing on a Map from above, but it certainly is easier to navigate thru than for example traditional Cloverleaf interchanges, especially at times with high traffic volume (at least if everyone is in their right lane).

Wow I'm so shocked you included the I-10/I-110 interchange in Baton Rouge. It came to my mind immediately but I never thought it would actually be in this video. Anyone between Houston and Mobile knows about that interchange. The interchange there accommodates the I-110 traffic going downtown and not the people staying on I-10. It's the worst chokepoint in Louisiana and maybe the worst in the Gulf Coast region, and yes that includes Houston. Baton Rouge has always had abnormally bad traffic for its size, and while there are lots of trouble spots, all of BR's traffic issues are displayed pretty well in that single interchange.

I worked for a consulting engineering firm as a cad technician under the supervision of the traffic engineer. I got to see the process of designing these interchanges. Two major interchange projects I worked on were I-80 at Cline Avenue and approximately 5 miles of I-65 north of the Ohio River which included interchanges with US 31, SR 62, 10th street, Sansifer Ave and Eastern Blvd. All of this project on I-65 has been reworked again since I worked on it. These interchanges look bad from the air or on a map, but they do work well for driving them when the signage is there well enough in advance of the ramp to get the traffic in the proper lanes for where the drivers intend to go. The most dangerous interchanges on the interstate system are the cloverleaf interchanges. They cause a weaving of traffic that is a choke point and a high accidents spot. Cloverleaf interchanges were meant to cut the cost of bridges in interchanges by minimizing them to one or two mainline bridges, but the on and off ramps using the same short lane to exchange traffic Is the problem. Ohio had a Cloverleaf at the interchange of I-70 and I-75. They replaced it with one of these spaghetti interchanges with multiple flyover ramps it works well. I used to use that interchange on my many trips between Indianapolis and Toledo. After having to make several runs around the cloverleaf before I could safely merge on to 75 north bound on two of those trips, I avoided that interchange totally by changing my route to I-69 and the I-80 Toll Road/ Turnpike. I actually found out that my new route was a little bit shorter and faster.

The grandaddy of weird and wonderful interchanges is the East Los Angeles COMPLEX of I-5 (former US 99), I-10 (former US 70), US 101, CA 60 (former US 60), with too many additional side-streets to be worth mentioning. Most of it has been standing since the 1940s and it is prone to jamming even in the middle of the night.

One of my personal "favorites" as a DFW (Dallas-Fort Worth) resident is the famous "Mixmaster" of interstates 30 and 35E in downtown Dallas. Unlike a normal highway interchange where a stack can be used, this one is spread out with so many ramps because of the way 30 and 35E intersect (they're practically merging for 1/4 mile). Another weird interchange is where interstates 40, 35, and 235 intersect in Oklahoma City. I've driven through OKC a number of times and that interchange always confuses the hell out of me even w/ GPS. The design isn't intuitive as you have to exit 35 to stay on 35 (otherwise you're headed onto 235 or I-40). Honorable mention to downtown Tulsa. What a joke of highway intersections.

My sister goes to college at Marist (just finished yesterday!) and every year for parent’s weekend me and my family have to navigate the horrors of US-9. This junction at 6:12 is a MESS.

So about the 10/110 split in Baton Rouge. It's not exactly the interchange design itself that's bad, but the surrounding geography and road network. The I-10 bridge (which the locals call the old bridge) is only the 6th road crossing over the Mississippi River going upstream and the first carrying a mainline Interstate. There are no real alternative routes across the river that don't send you hundreds of miles out of your way, so lots of cross country traffic flows through the urban core of Baton Rouge out of necessity. There are plans to put a new bridge up a few miles downstream near Bluebonnet Dr, but that's only going to connect the "west bank" communities of Plaquemine and White Castle to suburban southern Baton Rouge, hardly helping the 10/110 split. How you fix the 10/110 split is putting in a high speed bypass south of Baton Rouge that connects west of Port Allen to I-12 near Livingston. I don't live in Louisiana anymore, but I often joke with my friends any time I open up Google Maps that the old bridge is clogged with traffic. I'm usually right. Also, you want a weird interchange, just go 2 exits west of the 10/110 split to the I-10/LA-1 interchange. I've navigated it a few times and it's awful if you don't know what to expect. Edit: I didn't even mention the 10/12 split just a few miles to the east of the 10/110 split, the former interchange also makes the latter a nightmare, and if you're going west, you get funneled into a freeway that has to handle two metro regions of traffic and cross country traffic, so going west, the lack of lanes really hurts. It's not uncommon to see red on a traffic map from the 10/12 split to LA-1 on both sides of the freeway.

My personal "favorite" weird interchange is the Golden Glades Interchange in Miami. 6 highways and major roads meet there - I-95, the FL Turnpike and Palmetto Expressway both terminate there, US 441, SR 9, and 167th St. It also features a rail line complete with a commuter rail station, bus terminal, and parking at the southwest end of the interchange.

love your videos :) been watching for years

I’ve driven/been on most of the ramps on Birmingham’s Malfunction Junction interchange, and it has definitely seen improvements since they enhanced it. However, this is conflicted with some of the worst crashes you have ever seen and one of the most stressful merging jobs in the South. There have been several incidents of trucks botching the turns and going ablaze in the middle of the interchange, thus setting the interchange ablaze. Merging is just as bad; traffic heading east on U.S. Route 280 towards Auburn from I-65 South must merge over up to four lanes in less than two miles. This is definitely not the problem child it was a decade ago, but it’s not for the faint of heart regardless.

The Tampa Bay area is home to a few weird interchanges. I-275 at the Pinellas Bayway is one of the few places in the US where an interstate flips sides (northbound traffic on west, southbound on east) for a mile or so, but I'm not sure of the history of why this is so. At the south end of Tampa International Airport, there is a massive interchange over about a 1.5mi stretch of SR 60 between several major cross-bay highways (I-275, SR 60, SR 589) and several local roads, plus the central interchange's bridges must be low enough to avoid the most-used runway at TIA. Going south leaving the airport access road, there are SIX choices to make at the interchange (WB SR60, SR 589, SB I-275, Cypress Street, Spruce St, and EB SR 60 to I-275 NB). The southern end at the junction of I-275/SR-60 has major improvements planned, but will still be chaotic. Just east of downtown is a spaghetti junction of lanes connecting I-4 and the Selmon Expressway. Zoomed out in Google Maps, it may look normal, but zoom in with satellite view and it is all a bunch of 1-2 lane paths to connect the two highways along with a slip road for truck traffic to the Port of Tampa. The northern end has a few stubs to eventually connect to express lanes in the middle of I-4.

I think you should discuss some interchanges in New York. Some of them look very odd, especially some on Long Island.

Oooh caught this one early! Everyone loves some fresh beaver in the afternoon, and then there’s also a new geography video too! 😇

The 696 interchange can have traffic issues from all the westbound traffic being funneled onto 96 heading toward Lansing with lanes rapidly disappearing. Also heading on 96 East toward the interchange, there's issues with a lot of Novi road traffic merging onto the highway right when you want to get over to head south on one of the highways

Hey @BeaverGeography , I really enjoy your videos and explanations of our national road system.

I'm really surprised you didn't mention the I-196/US 131 interchange in Grand Rapids. It's basically the same design as the I-65/I-20/I-59 interchange in Birmingham, except that only US 131 crosses over itself, and the interchange is significantly more compact due to its proximity to the Grand River. I can attest that jockeying to the correct lane can sometimes be a struggle, and the weaving between it and the Pearl St interchange sucks. Other weird interchanges in Michigan are: The I-69/I-96/I-496 interchange and the I-69/I-96/BL I-96 interchange in Lansing, both due to how large they are with the former being originally planned as the location where I-69 would split off. The I-96/US 131/M-37 interchange in Grand Rapids. The exits from NB US 131 and EB I-96 are actually I-296, the only part of the unsigned interstate that is not concurrent with US 131. The I-75/US 23/I-69/Miller Rd/Bristol Rd interchange in Flint. This complex is slated to be redesigned sometime in the future to help ease congestion. The I-94/M-10 interchange and the I-75/I-375/M-3 interchange in Detroit. The former is the oldest freeway to freeway interchange in the US, and is slated to be redesigned. It's like the Birmingham interchange, but neither road crosses over itself. The latter is weird because it wasn't designed to accommodate I-75 as the mainline. In order to stay on I-75 you must make a tight hairpin turn to continue north. A truck actually tipped over and caught fire here once. When I-375 is decommissioned, I expect that this interchange will be reconfigured.

So... humorously the stack Interchange you show at @1:15 mark (US183 and Mopac expressway in Austin) was photographed for a long exposure Car and Driver drone pic that was in the January 2023 issue. Because I was bored, I figured out where it was from and wrote a letter to the editor. That got me Letter of the Month for June issue and a set of Winnebago coffee mugs.

I-85/I-285 northeast of Downtown Atlanta. It’s called spaghetti junction for a reason. Afternoon traffic there is some of the worst in Atlanta.

I LOVE HOW YOU OWN YOUR LISP! YOU‘RE DOING AN AMAZING JOB, KEEP GOING!

Thanks!

1:49 oh my god that's like a home interchange for me! I live in madison and always use this interchange when i can because it's so etched in my memory, we would use it frequently when my family would come down from Stevens Point and now I use it when I go back to them. Love the good ol 90/151 cloverleaf

The Poughkeepsie interchange was so stressful my Uber driver got confused trying to drop me at the Poughkeepsie station just to the north

The problem I see with these junctions are the extra on/off ramps connecting to the street level making them more complicated than they should be.

I can't count the number of times I've navigated spaghetti junction, and it's still beyond confusing. No matter what you do, you're never in the lane you're supposed to be in!

Suggestions for next episode: Mixmaster in Dallas the true Spaghetti Junction in Atlanta as others have mentioned, I-24/65/40 in Nashville I-70 with downtown Kansas City

I10 in Baton Rouge is a nightmare. Traffic is backed up for miles at all hours of the day.

hey @beavergeography the final stretches of i-88 heading towards chicago are filled with weird intersections such as i-88, i-355, and us-34 i think. very weird area as there are two sections where two separate highways run next to each other for miles (and it’s always under construction 😭) edit 1: forgot to mention that there is a whole neighborhood within the i-88 and i-294 interchange edit 2: the whole interchange northeast of ohare is diabolical to drive through as well (i-90, i-294, i-190, sr-72, us-45, us-12, devon avenue and river road all in a bunch of interchanges so close that they become one)

if you do this type of video again talk about the Grandview triangle in Kansas city

One weird interchange is I-27/us-287/us-60/us-87/I-40 in Amarillo. Unlike most of the interstate junctions in Texas, I40/I27 uses a turbine interchange, not a stack. the US highways get split up into a series of one way surface roads through the downtown on the north end of the interchange, which is less than ideal these days as the city is trying to make downtown more of a recreational/residential area instead of just offices and all the heavy duty agriculture traffic using those roads as highways through town make the area loud and smelly. The turbine is actually a rather nice and functional interchange, especially after a flyover ramp connecting I-40 E and I-27 S was built a few years ago.

I remember when i was a little kid after my therapy, my mom and I always drove into the Dolphin-Palmetto Interchange to get onto Dolphin Expressway east to pick up my dad from work. Let me tell you, it used to be an absolute nightmare! There was so much traffic that sometimes I would play on my Nintendo DS to pass the time.

Great video! Can't believe you missed the Bruckner Interchange in the Bronx, it really is a doozy! Maybe I'm just biased though...

My two favorite interchanges is the 1-10, I-5, us 101 and ca 60 interchange south of downtown Las Angles and the second one is I-10 us 90 interchange in New Orleans. They are both crazy.

Ldot is just starting their multi year expansion of i10 plus another Mississippi river bridge near Port Allen. Ldot needs to severely finish the loop around Baton Rouge

If you know the area, Malfunction Junction is actually pretty smooth to drive through after the additions. It's not like other rough interchanges where it's rough even if you know the flow. The state had withheld funding completing the interstates around Birmingham for a long while (George Wallace wanted to punish political rivals from the area). So the interchange is actually from the 70s. Its design came after seeing some pitfalls from earlier designs (and like other intercity interchanges, was displacing a lot of people. So it was minimizing land use a bit). Still not great, but I'd rather deal with one annoying navigation spot in Birmingham than the mess that is Nashville's roadways (Atlanta's annoying due to traffic, but the layout's decent. Nashville, though...).

dr beaver, the only sensible civilphile on yt, cheers!!

The Kennedy Interchange in downtown Louisville's waterfront is a 5 direction interchange with the through moving highways I-64 E/W and I-65 N/S and I-71 whose western terminus is at this interchange. Before the rework and untangling of the interchange it was titled spaghetti junction; however, with the addition of the NB I-65 Abraham Lincoln Bridge it was renamed the Kennedy Interchange as it did improve the junction over all by lengthening short merges, removing a few (not all) left hand exits, improved signage, and the introduction of tolls across the Ohio river on I-66 NB and SB. The traffic through that intersection itself is not bad. The introduction of the toll across the bridge has decreased major traffic through the interchange; however, there can be backups of traffic leading up to the interchange as people get off I-65 NB to enter the downtown grid to take the George Clark Bridge (US-31, un-tolled). Living in Louisville I am happy with the rework and I don't feel the need to avoid this area if I have to go through it.

285 and 85 North of Atlanta will be a monster when its finished

Hey! Sponsors! A sign you’re getting some traction. Great channel!

Each of the four interchanges in the Tulsa downtown are crazy due to how crammed in the lanes are

Some other good ones I know of are I-10 / CA-60 / US-101 / I-5 in Boyle heights, I-5 / WA-16 / 38th st / Sprauge in the nalley valley, and CA-15 / I-805 / CA-94 in fairmount park.

I see you have stills of the Palmetto Expressway west of Miami. That reminds me of the Golden Glade interchange, where SR 826 (Palmetto Expressway), I-95, Florida's Turnpike, SR 9, and US 441 meet. There is an HOV flyover on I95 that's so high you can see the ocean. As for poorly designed there is the Florida' Turnpike Don - Shula Expressway interchange. 5 lanes across entering the interchange southbound, with 3 going to the Don, and 2 thru traffic for the turnpike. The turnpike gets backed up as cars and trucks share the road. Needs expansion.

The interchange between I-480, I-71, and OH-237 in Cleveland, OH, is quite crazy due to the amount of incomplete connections (eg. the lack of I-480W to I-71S, I-480W to OH-237N, I-71S to I-480E), as well as 237's right of way being forced onto a surface street and going concurrent with OH-17 for a short time. The only clean workarounds are by going to Grayton Rd. and connecting with I-480 there or by connecting with Snow Rd. at 237 or 71.

Nomination for next episode: US 61 and Causeway Blvd., Metairie, Louisiana. It's a tri-level interchange. The first level is US 61 E/W on the ground, Causeway Blvd. flies over it all N/S at the third level. The second (middle) level is where all the fun is, because it's absolutely a large perfectly circular elevated roundabout, built many decades before the roundabout craze hit the USA, with ramps up and down to and from the other levels. Oh, there's also a double-track railroad running diagonally through one edge of it between highway levels one and two.

Another interesting one is the portland I-84 I-205 interchange. It's weirdly long, and runs both higways parallel to eachother for a mile. It also has many tunnels and is partially in a large hill

Im surprised that there were some seriously disfunctional interstate interchanges that were not mentioned here. Also compared to the old malfunction junction in B-ham, this new one you showed is great. Traffic flows and it's much safer as well. All in all these were some pretty good interchanges.

I drive thru Malfunction Junction in Birmingham on the regular and while there have been improvements over the years it’s still one of the wildest designed interchanges I’ve driven through. The amount of left lane exits are abysmal combined with a lack of a loop road or alternative route for trucks and pass by traffic to avoid the city makes it even worse. On the bright side the first phase on a road project for an outer loop around Birmingham is going to start back up soon but the downside is that the entire project isn’t slated to be completed until the 2050’s

America is becoming very dysfunctional & unstable. Our country seems to have zero interest in improving the lives of its own citizens. That is, our cities feel disconnected, soulless, bland, unaffordable, etc. I really don't like the direction modern America has gone. We could do so much better. I love this country. I just want to see things improve. i loved how in the 90's we at least had all sorts of places that people could live, unique things to do & places to go. Poor People, middle, upper class. There were places for anyone ~Nowadays we have universally unaffordable cost of living, rent prices, shop rent prices.. (unless you are wealthy) I don't understand how long we can continue to function in this extremely dysfunctional manner?? I hope things change. People stuck in poverty need places to live too.. it's ridiculous how our current system pretty much requires everyone to be financially well off 👍🏻 Yeah, that's so realistic (Not)👍🏻 it's completely impossible for everyone to be financially well off. We need living options. We need places that average people can live, poor people can live.. Raising wages just continually makes things worse because our country says "it Has to increase things" if minimum wage goes up. So it does nothing but make things worse. We need places people can live even if they make below average $ (look at all the rent prices right now? The same goes for the rent of local small businesses too. It's absurd. I know this because my mom runs a local small business in Oregon. So that's 2 insane rents to pay per month! It's the biggest challenge to afford rent. Profit isn't even really a thing. How stupid is that? What kind of quality of life is that?) This is Modern Day America 👍🏻 and when you look at our government, it doesn't seem like anything is going to be addressed or improved anytime soon.. Maybe multiple generations from now, idk?

The Fort Worth mixed master. That's an interesting interchange.

I live in Louisville KY and spaghetti junction was way worse before being rebuilt for the new bridge. A much worse interchange in Louisville is the on at I65 and i264. The way it was rebuilt in the 90s was awful. When heading west, at rush hour, most traffic wants to go South off of I264, but the interchange has one lane South and two lanes North. The opposite of what the traffic flow wants. Coming South on I65, it's the same thing. Two lanes going west and one lane going East. At rush hour most traffic coming South wants to go East.

You should do the I-84/Route 8 interchange in Connecticut!

Definitely could make a part 2. The I-90 and I-5 Junction south of downtown seattle is insane to see/ drive through . East of the interchange eastbound I-90 divereges into 2 separate tunnels from the original tunnels built in the 40’s. And going westward they built I-90 through a valley into a double decker tress that spans (I think) 100 feet over the city and directly links you next to the stadium Ever since this interchange has been built it is well known to be notorious for going northbound exiting from westbound I-90, since it’s inception it is consistently backed up throughout the entire day, Washington’s dot actually addressed this and managed to put in an extra lane recently

I have to take the I-10 I-110 interchange sometimes for work and I can tell you that it’s a mess, I go from westbound I-10 to northbound I-110 which has 2 lanes that quickly becomes 3 with an on-ramp off to the side which isn’t challenging but twice when I came back from southbound I-110 to eastbound I-10 there was too much traffic so I just had to go westbound and cross the bridge and went north on the next exit until I crossed the Huey P Long bridge back to get to highway 61 and take that back instead with less traffic since I already took 2 hours to get there and I didn’t feel like taking 4 hours to get back

I've driven through Baton Rouge many times to get to Alabama. That interchange took us a while to get past it. Slow traffic until the I-12 interchange. But tomorrow I have to go through Boston

As a Louisiana resident the I-10/110 interchange isn’t as weird as you get used to the area via driving, even though the traffic on the overpass to get on I-10 toward I-12/New Orleans from the Mississippi River bridge is bad, LaDOTD is currently finding solutions for this problem

How many “malfunction junctions” are there in the US interstate system?

US-75 southbound to I-35 southbound in Dallas is probably the longest "off-ramp" in the world, if you follow the posted signs. The I-69/I-45/US-288 exchange in downtown Houston ends up causing probably all downtown traffic that isn't caused by I-610 having horrible interchanges. If you're going through the first of those two exchanges, southbound on I-69, something like 10 lanes of traffic get smushed down to 2 before you can get through this bit of road.

One you may want to look at is in Minnesota, at the junction of MN 5 and MN 55; this interchange is hemmed in by rivers, bluffs, parkland, historic sites, an airport, and federal property.

One of my favorites is the Huntsville I565 parkway, mostly exit 19, but unique in that It has 6 different overpasses at one point

Born and raised in the poughkeepsie area, 28 years later, i still avoid that interchange like mad. Its basically a meme in our area. There are also still studies being done to completely rebuild the junction with at least 3 concept designs (can't find the link :/ ). Fun fact: the rt 9 expressway thru poughkeepsie was an early pre-interstate incarnation of the long dead interstate 487 meant to run between tarrytown and albany (the later 487 design in the 60s was cut back to i-84 near beacon) Check it out if ya can 🙃

Another one that comes to mind is the interchange of I-83, I-283 and US322 in Harrisburg PA part of the city's "beltway". Old bridges, tight ramps, and not much advanced notice of which lanes go which direction.

I'm not from the us but the interchange near Newark airport is completely unbelievable

There are other wired interchanges such as; l-35 @ l-90 in Minnesota, l-39 @ l-88 in Illinois, l-69 @ l-80-90 in Indiana, l-69 @ l-94 in Michigan, l-10 @ l-75 in Florida, l-26 @ l-95 in South Carolina, l-40 @ l-77 in North Carolina, l-40 @ l-95 in North Carolina, l-70 @ l-77 in Ohio and l-79 @ l-80 in Pennsylvania. Because all of these interchanges were built in the middle of nowhere. It's scary that these interchanges exist without there being a city near these interchanges.

I’m surprised I didn’t see the Eisenhower interchange between the Capital beltway and US 322 didn’t show up that’s a mess. They had limited space to work with and it’s genus with the space they had. Sadly they are starting to build express lanes on the beltway and demolish buildings so the interchange will be no longer over the next 5 years. Also why no Breezwood?

A favorite weird intersection of mine is found in the remote U.P of Michigan as US 41 meets M26. The one thing about it that Google Maps doesn't really capture in the odd design is the way the stoplights interact with the flow.

I-85 / I-485 at the Charlotte Airport. Going from 485 south onto 85 south is a total bottleneck and NCDOT admits they goofed even after the same thing happened in Raleigh (which they sort of fixed).

@beavergeography In Connecticut, the interchange of I-91, CT-15, I-691, CT-66, East Main Street in Meriden, CT has 1-2 crashes per day on average. Take a look at it!

78 and the NJ TP in Newark is so confusing, include it in the next video like this

Honorable mention to the I-69/I-465 interchange being built on the NE side of Indianapolis right now. Looks crazy haha

1:24 That stretch of state highway going north from the interchange was originally supposed to be an extension of the north-south interstate

As someone who has laid out dozens of interchanges in the US, I understand how they can seem random, and confusing - especially from top view. Thankfully, people don't drive that way - they encounter decision points, and if well marked, drivers can make informed decisions. Connections between freeways are based on route continuity - or providing the most efficient path for the most people. Tools for these connections vary from direct connections (flyover ramps), or semi-direct (loops), as well as linking facilities called collector-distributor and auxiliary lanes to shield the main line traffic from the "turbulence" of entering/exiting traffic. Many of these are out of date based on shifts of population and commute patterns, or have been incrementally updated.

Malfunction Junction was also improved a bit when they expanded and modernized the I-20/59 viaduct through northern downtown Birmingham. The connections from to the interchange were improved. It runs a lot smoother now. Even if it looks confusing on satellite. lol. I believe this work finished in 2021. But I don't remember exactly.

I-20 and I-35W interchange in Ft. Worth, TX. The problem part of this one is exiting onto south I-35W from either direction on I-20. Westbound I-20 exits onto a very tall two lane overpass. Northbound I-35W traffic breaks off pretty quickly, but Southbound stays on the exit. Despite being two lane over the entire overpass it merges into one lane at the very end. You then have to very quickly move over two lanes to stay on southbound I-35W. The lane from the overpass plays out very quickly, and the next lane over is an exit only for the next exit. Additionally, traffic for southbound I-35W coming from eastbound I-20 merges in right at this same point, and those drivers have to move over three lanes. This all happens in an area where traffic on southbound I-35W is already backing up, so it's just a mess a lot of the time, and very stressful as southbound drivers generally don't want to let people from the on ramps merge in.

gotta check out the macarthur maze into the 580, 980, 24 interchange in oakland, ca. i pretty much always see a crash, its a mess

yoo i live in poughkeepsie. crazy to hear my town mentioned. I will agree, that intersection is a mess and I always second guess if I'm doing it right lol.

I've been through that interchange in Michigan and didn't even realize it because we went through so easily lol I was coming from grand rapids to windsor, ON

the first one is apparently the biggest interchange in the USA by area, Citynerd did a video about this 😂

I was waiting for the Turbine interchange in Amarillo to be covered...somewhat iconic and apparently somewhat dangerous

The Springfield Interchange between I-95/I-495/I-395. It genuinely looks atrocious, and the traffic on it is horrid. But driving it isnt all that confusing. Its also a massive size.

I-30, I-35E, and Spur-366 interchange in Downtown Dallas is so terrible and confusing, some of it isn’t signed accurately either

Maybe another interesting video could be how Texas is building 4 lane and 6 lane Toll roads in the center of it’s interstate highways, overlapping in some cases. A good example of an amazing interchange not mentioned here with a double interstate highway and toll road layout is the “High Five interchange” in Dallas Texas. It’s at Interstate 635 and US75 and is considered one of the biggest, most expensive interchanges built. Texas is investing billions to extend this all the way around the city, as well as I35 E north of Dallas to Denton and I35W north of Ft Worth.

Few honorable mentions for the Miami area is FLTP/I-595/441, or I-95/SR-826/441/FLTP, or I-595/I-75/869

I lived in Birmingham for 43 years. Malfunction Junction is all you said and so very much worse.

I drove through that interchange in Novi, Michigan....I always wonder y it's like that...

Look at I-85/I-285 Southwest Corner in Atlanta

I'm surprised that the Boyle Heights Interchange in Los Angeles did not get mentioned. The freeways of I-5, I-10, U.S. 101, and S.R. 60 (formerly U.S. 60) all come together at this point. It looks like a mess on any map. One needs to pay constant attention to the signs. Once on it, it seems to go on forever.

Interesting that interstate map you showed at the beginning has I-57 going north all the way to Green Bay...

I saw the "turbo roundabout", I clicked.

I-10 and I-110 in Baton Rouge- 365/24/7 eastbound traffic is backed up across the river for miles. There's perpetual construction being done on I-10 so that compounds the traffic. Then, God forbid, there's a wreck on the east side of the river or on the bridge. There's no circumventing this interchange that I know of and it's compounded even more by the fact that it's part of the major East-West interstate along the southern corridor from Florida to California.

Not really an interchange, but the Dorsett Road exit on I-270 in Missouri is the weirdest exit I've been to. Traffic on Dorsett crosses over each other, so you drive on the left while going under the interstate!

Consider: 1) The Spaghetti Bowl at I-495/ I-95/ I-395 in Springfield, VA just south of DC. 2) The U.S. 50/301 and Md Routes 2 and 450 interchange in Arnold, MD.

Marquette Interchange enters the chat

that 696 corridor in detroit is buttery smooth. 696 is prob the smoothest/fastest flow in all of metro D

I think the I-696/US 24/M 10 (Lodge Freeway)/Lasher Rd interchange a few miles east of the interchange in the video is worse... It's nickname is The Mixing bowl Lasher Rd. is the next county mile road to the east of US 24 (cardinal direction is north/south in Michigan)...At one point in the interchange, both I-696 carriageways are in the median of the Lodge carriageways...Many cloverleafs, flyovers, and even a couple frontage roads are in the mix
