Jeff Ostoff shows you the latest updates on the engineering disaster aftermath of the MV Dali ship striking the Francis Scott Key Bridge causing the bridge collapse in Baltimore, Md. on the Patapsco River. The video also shows some design concepts for the new Key Bridge to replace the old Francis Scott Key Bridge. You'll also see the incredible new massive underwater hydraulic claw in operation, dredging up massive sections of bridge debris of the now re-closed channel. They closed this limited access channel on April 29, 2024, after the first ships to pass through the new limited access channel, a deepwater 300 ft wide, and a 35-foot deep access channel for larger ships, the first time since the MV Dali collided with the Francis Scott Key Bridge in Baltimore, MD on March 26, 2024. You'll see progress so far in this Baltimore bridge collapse.

They barge the bridge collapsed bridge debris to the new 10-acre laydown yard used by the U.S. Army Corps of Engineers to process wreckage from the Francis Scott Key Bridge site. An estimated 50,000 tons of concrete and steel collapsed; once removed, the wreckage is sorted and transported two miles away by barge to Sparrows Point. Debris and wreckage removal is ongoing in support of a top priority to safely and efficiently open the Fort McHenry channel.

they used a diamond wire saw to cut the bridge support. The drive unit can be seen on the deck of the Dali in that image, right above the concrete slury marks on the hull. Its the baby blue colored box with the black tire and grey spools on the side. They used a similar process to cut the Diamond Ray shipwreck apart, but in that case they used a diamond coated chain as a hack saw, with 2 cranes as the power source.

@richardhartzell7059 Месяц назад

2 of the most recent cable stayed bridge jobs in the US -- both look nice - but took 7 years to build .... The NEW GD bridge in Long Beach main span is only 1000' -- which is even less than the old Key Bridge 1200' span. The new Gordie Howe Bridge b/w US and Canada-- span wise is more similar to what they need to replace the Key Bridge with a cablle stayed bridge. The Tappan Zee bridge job was the fastest large US cable stayed bridge built recently -IT got built in 4 years A main reason for TZ's faster speed was their use of a crane called the LEFT COAST LIFTER -- which is about twice as big as the "Chessy 1000" --- and thus could do build things almost twice as fast.

@argusfleibeit1165 Месяц назад

The design they showed was very pretty. But my first thought was, with all the cables strung from the center of the roadway, there is no way to drive any kind of emergency vehicle between the two sides. Or if, for example, it was necessary to adjust for traffic from morning to evening rush hours, there would be less flexibility in changing number of lanes going in each direction incoming or out going. We have bridges in Pennsylvania that can have lanes changed over from morning rush hour to evening rush hour, by red and green lights built into the trusses over the traffic. The volume of traffic demand can be adjusted just by changing how many red or green lights are lit up.

I remember when the first original proposals for the "Outer Harbor Bridge" were published in the Baltimore Sun, circa 1970. It was nearly identical to the design they are now calling the "new design". But it cost too much, and they went with the much cheaper truss bridge, with the narrower center span giving no margin of safety around the ship channel.

@KennethAGrimm Месяц назад

@@h8GW Back then, the reporting in the Baltimore Sun etc referred to the original design as "a suspension bridge with a radical new design". The biggest cost issue, however, seems to have been the length of the main span. The cost does not simply increse linearly with the span; the cost is more like the square or even the cube of the span. Also, the cost per span-length scales differently for suspension and for truss.

I wouldn't put it in doubt that this accident will influence the MTA (the agency that oversees all of the toll highways and bridges in Maryland) on their project to replace the Chesapeake Bay Bridge between Annapolis and Kent Island on the Eastern Shore. Currently the biggest issue on the CBB is the traffic (especially commuter and summer traffic), but with Carnival Cruises operating out of the Port of Baltimore, besides the height, you have to worry about possible collisions (and unlike the Key Bridge, the replacement CBB's main span would have to be a suspension bridge similar to the 1915 Çanakkale Bridge in Turkey, the Great Belt Bridge in Denmark, or even the Verrazano Bridge between Staten Island and Brooklyn - being with a center span longer than the current 1,600-foot center span utilized by both of the current bridges).

I said within the hour of the bridge collapse it would be replaced by cable stay, it would accommodate a wider channel, but, between 2000 and 2005 the MDOT announced they were building a cable stay bridge. So... of those that don't know the history of Cable Stay Bridges, they were innovated immediate post WWII in Europe to address all the bridges the US dropped during the war. Erecting a Cable Stay Bridge can for the size required can be 2 years start to finish, IF a Cable Stay Bridge specialized company does the work. They often have a set design for the masts that can be tailored (read shortened) easily to fit the needs. Nothing starts until the bidding starts, lowest bidder won't get the bid, the organization that can prove they have the capability to do the job starting 'today' and has a track record of delivery on time on budget and on design, they'll get the contract.

@geneard639 Месяц назад

and, I doubt anyone will ever come close to an incident in Jacksonville Florida where a 30 foot 2 lane bridge collapsed and the company putting up the new sky way for I-95 was asked "can you give us a bid" and they said "We can do it in a few days with excess road panels", but they still put in a bid. They used two pre-fab road panels and some spare concrete pilings. 4 days. The city gave them 3 months, they did it in 4 days. 1 day to demo the old bridge, 1 day to put down the piles, 1 day to lay the road panels, 1 day to pain the stripes and inspect it, 4 days. Company? Cited zero materials outlay, only expense was fuel and labor costs. The company got paid for the 3 months work, plus an on time, on budget, on contract bonus. Company? Gave the workers the whole pot of money for working non-stop, damn near 24 hours a day for 4 days to get the job done. Old bridge was 2 lane asphalt over wood, new bridge 4 lane reinforced concrete. Everyone was happy.

I would like to see a discussion of the comparison of the longevity, strength, durability, cost, etc. of the cable-stayed bridge versus the traditional bridges such as truss and suspension construction. It seems everyone is installing cable-stayed brisges theses days. Are they as safer and more cost-effective???

@tomwujek4867 Месяц назад

Yes they are. Trusses have fracture critical components and lack redundancy, whereas cable stayed bridges eliminate that issue on almost all designs (unless it utilizes a double deck). Also, cable stayed bridges require less material, are as strong or stronger than truss designs, sway less, and are much simpler to maintain over the life of the bridge. A major advantage is a cable stayed bridge is designed for cable loss. If some cables were to fail, they can be replaced pretty easily and in many cases with only minor lane restrictions.

The only time we could go through the tunnel was when there was zero visibility on the pass and then it was only at the top of the hour when they would stop all the traffic and let the tankers go

They probably use the cable saw which is a cable with diamond impregnated pieces into the cable they use them in quarries to cut marble

Good bridge to look at is the Gordie Howe bridge, there is a good channel that has all drone footage closeups of the construction techniques. One major point about that bridge design is that to increase ship headroom, the on/off ramps had to be extended considerably to avoid steep inclines.

My guess was the concrete pier at 01:30ff was cut using a water jet. But some smarter than me people spotted a diamond wire saw. :)

Hi Jeff, I am Jayatissa from Sri Lanka. I am very much interested in the engineering side of the salvage operation of FSK bridge. I need a clarification as to how that giant claw-"Gus" was transported from Galveston Texas (so I hear) to Baltimore and how was the Claw taken to Chesapeake 1000 from the river bank?

Most new bridge designs with a large span are going to this style. It’s a fast build, and majestic. Cable stays and traditional suspension bridges are my favorite.

No mention that it's a similar design to the Skyway Bridge over Tampa Bay?

I wonder what'll happen to the drawbridge nearby when they widen I-695. Maybe that'll get replaced with a fixed span?

The single cable stay looks to allow twisting in wind events. Must cable to each side to avoid.

@gordmcdonald2807 Месяц назад

The proposed bridge looks like the new Gordie Howe bridge currently under construction joining Detroit Michigan and Windsor Ontario. The 2 sides are almost joined.

@judith1c 11 дней назад

Sorry if I missed you covering this... but did they propose making it higher as to allow larger ships in?

The cutter is literally in your shot... The blue box at the top left of the cut. You can even see how the angle of the cut changed as it was almost through.

Webuild has been building bridges according to their website for 120+ years. Their US subsidiary Lane Construction has also handled many complex projects successfully, including the I-495 Capital Beltway Express Lanes in Virginia. That was a 14 mile project which replaced more than 50 bridges and upgraded 12 interchanges. Webuild is actually doing a hydraulic tunnel project under the Anacostia River right now for DC Water. Besides bridges/transportation, they also have experience in buildings and power/energy projects.

I just got back from Bangkok Thailand and they have several of these cable bridges there. In fact I was able to walk across at night one of the bridges and the lighting at night was awesome. Of course walking across a much bigger bridge is probably not an option here in the US.,,,,,,,,,

Nice modern design of new bridge shown. However there is no protection for the bridge supports against the next ship having a navigational problem.

@matzrat5006 Месяц назад

With the two 500 feet expansion on both sides and Tugs leading the Ships in and out of the Harbour, will be a huge safety improvement.

@tomwujek4867 Месяц назад

The interpretation is that they are going to enlarge the actual shipping channel (main span) to 2,300 ft. That'll mean the main pylons of the bridge will be about 500 ft further back on either side compared to the original bridge which increases safety. Also increasing the vertical clearance to 213 ft will accommodate almost all major ships in existance today.
