Engineering is awesome! Angled highway bridge! A9 Schipholbridge Holland 

Some boats go to the left others to right.

The engineer who designed it, smoked to much grass.

EnigmaDrath If that was the case then they could still open it in the same plane as the road. The angle is just decoration.

True you could still just open it in the same plane as the road, but then you're either not lifting up the entire cross section with the waterway (which is an accident risk) or you're lifting up more of the road than needed(which makes both construction and each operation of the bridge more expensive). The angle exists to minimize the amount of road deck being lifted while not introducing a collision hazard for the ships passing through.

HummingLoud Probably is more quick to open and close and more efficient in power or material costs.(less counterweight required) Imagine it like a balancing beam, you shift weight to 1 side for it to drop and other side to lift. The more length you need to lift, the more counterweight you need and power to shift that counterweight around.

Because the canal isn't crossed at a 90 degree angle by the highway. Any other solution would have meant: * - A wider bridge, or a narrower canal . *- Or bends in the highway, or bends in the canal. Here is another one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Bxh3S5Ov5nE.html

Probably because that would have taken much more space and/or have been much more expensive.

High bridges are loud. Trucks rev up the engines to get up there and from such a high point the noise reaches much further. If anything else, an aqueduct or tunnel would be the suitable alternative. You see a lot of them in the Netherlands.

Talking about noise. This bridge is on short final rwy 27 at Schiphol

+Maarten de Graas What do you mean, "Loud?" I can't hear anything from the bridge with this loud music going.

+Maarten de Graas (above me) What do you mean, "NOISE?" I couldn't hear anything from the bridge with this loud music playing. I had to mute it, so I don't go deaf.
