The U.S. 61 Bonnet Carré Spillway Bridge is a twin concrete trestle bridge in the U.S. state of Louisiana.[1][2] It has a total length of 1,830.62 metres (6,006.0 ft). The bridge carries U.S. Route 61 (Airline Highway) over the Bonnet Carré Spillway in St. Charles Parish.

The original span currently serves eastbound traffic, while the newer span serves westbound traffic.[3]
