Kansas City Southern Bonnet Carré Spillway Bridge

The Kansas City Southern Bonnet Carré Spillway Bridge is a bridge that carries a Canadian Pacific Kansas City rail line over the Bonnet Carré Spillway in St. Charles Parish. At 1.8 mi long (or 9,501feet), its length once had it included on the list for longest bridges in the world.

The bridge is owned and maintained by the Canadian Pacific Kansas City Limited and is used by Canadian Pacific Kansas City (CPKC) freight trains. By 2015, speed limits on the bridge had been reduced to 10 mph. It is proposed to be reconstructed and upgraded as part of Amtrak's proposed New Orleans–Baton Rouge passenger rail.
