The Atchafalaya Basin Bridge, also known as the Louisiana Airborne Memorial Bridge, is a pair of parallel bridges in the U.S. state of Louisiana between Baton Rouge and Lafayette which carries Interstate 10 over the Atchafalaya Basin. With a total length of 96,095 feet (29,290 m; 18 mi; 29 km), it is the 3rd longest bridge in the US, the 2nd longest on the interstate system, and fourteenth-longest in the world by total length.
The bridge was opened to the public in 1973, construction was said to have begun in 1971. At the time of its completion, it was the second longest bridge in the United States, behind the Lake Pontchartrain Causeway Bridge. The bridge includes two exits: one for Whiskey Bay (Louisiana Highway 975) and another for Butte La Rose (LA 3177). While the bridges run parallel for most of their length, they merge when crossing the Whiskey Bay Pilot Channel and the Atchafalaya River. The average daily traffic count is (as of 2015) 30,420 vehicles.
