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 1830.62m (6,005.97feet). The bridge carries U.S. Route 61 (Airline Highway) over the Bonnet Carré Spillway in St. Charles Parish. The original bridge opened in 1935 serving four narrow lanes of traffic; however, due to frequent traffic congestion and accidents, a parallel span opened in 1984. The original span currently serves eastbound traffic, while the newer span serves westbound traffic.[3]
