longest vehicular bridge

[globocentric]

What's the ten longest vehicular bridge in the world regardless of whether it's a suspensions bridge or whatever bridge? I was given to understand that it's a causeway in the USA or something almost 30 km long

You're right,the longest bridge in the world is the Lake Pontchartrain Causeway,that is 38.41 kilometers long.You can find more information about it here: http://en.wikipedia.org/wiki/Lake_Pontchartrain_Causeway

^ Wasn't it severly damaged in the storm? I saw helicopter news footage that clearly showed large gaps in the roadway on at least on side. Looked pretty bad.

Those are the longest causeways, here are the longest floating birdge spans. The Akashi-Kaikyo Bridge, the world's longest suspension bridge span, is 6,527 ft. at its longest span.

In China, there are a few bridges that are over 30 km under construction right now!

What exactly is the benefit of these floating bridges, and why aren't there more around the world? I mean, those lakes must be awfully deep for them to not want to build piers.

They should build a bridge linking Delaware with New Jersey. The Freedom bridge. Would have 2 lanes in each direction. Would have call boxes ever 2 miles. would extend the garden state pwy an extra 17 miles. would be the longest bridge on the east coast. it would be a cable stayed bridge for the main span and a truss bridge for the apporachs to cable stayed bridge.

Lake Washington & Hood Canal (which is a fjord of Puget Sound) were both carved by glaciers & really deep.
