The collective image of a bridge in the United States is likely a pair of towers looming over a road deck. The deck is suspended over water by massive cables strung between the towers and anchorages at either end of the bridge. The scale of these bridges is astonishing as you drive across them. No matter what you’re driving, you feel like an ant passing through the towers reached up into the sky. However, if you look at a list of the longest bridges in the United States, you won’t see suspension bridges near the top.
Technically, the Lake Pontchartrain Causeway is the longest bridge in the United States. The country’s three longest bridges are viaducts, a roadway elevated by thousands of concrete pilings. I don’t want to come off as a bridge architecture snob, but suspension bridges are better than viaducts. I know that every bridge design has its place and purpose, but suspension bridges are just visually more interesting.
Here’s a list of the longest suspension bridges in the United States. The bridges are ranked by the length of the longest span, so no viaducts.
