The longest bridge in New Orleans, and other counter-intuitive bridge facts!

(1/3) > >>

MCRoads:
Here is a counter-intuitive fact: the longest bridge structure in the US is NOT the Ponchatrain Causeway. It is, in fact, on I-55/I-10/I-310. It is 14 miles longer!

Here are the google maps directions for proof:

I-55/I-10/I-310: https://goo.gl/maps/QFbWkzBYkNEBPwq6A
Ponchatrain Causeway: https://goo.gl/maps/vFrEqCenaKwdvPLB6

Edited to add: This bridge structure is 4 miles longer than the longest officials reccognised road bridge, in Bangkok!

Anyone else got any facts about bridges that don’t seem right?

Roadgeekteen:
I wonder why they don't count it as a bridge.

I think because technically it is 3 bridges that connect to each other via smaller connector ramps. The bridges are the Manchac Swamp Bridge on the I-55 portion of the structure, the I-10 Bonnet Carré Spillway Bridge, and an unnamed bridge on the I-310 portion of the structure.

just fyi, the 310 bridge is called the "Labranche wetlands bridge"

So, the longest bridge is actually three short bridges.
