The Atchafalaya Basin Bridge, also known as the Louisiana Airborne Memorial Bridge, is a pair of parallel bridges in the US 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) or 18.2 miles, it is the second-longest bridge in the US and fourteenth-longest in the world by total length.
The bridge includes two exits: one for Whiskey Bay (LA 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 2011) 24,540 vehicles.
Accidents occur frequently near the two river crossings as both are very narrow and lack shoulders. In 1999, Governor Mike Foster lowered the speed limit on the bridge from 70 MPH to 60 MPH. In 2003, the Louisiana Legislature enacted new traffic regulations for the bridge. The speed limit for 18-wheelers was lowered to 55 MPH, and they must remain in the right lane while crossing the bridge.
The United States Army Air Forces was created by executive order and the 82nd Airborne Division was formed at Camp Claiborne, Louisiana in March 1942. One of the main objectives of the division was for paratroopers and glider borne forces to seize bridges for regular forces to use. The 82nd Airborne Division Association put forth a challenge in 1988, to member chapters in all states, to pursue having a bridge in their state designated as an Airborne Memorial Bridge.
The Acadiana Chapter of the 82nd Airborne Division Association, created January 1980, in Lafayette, Louisiana with headquarters in Duson, Louisiana, petitioned the Louisiana Legislature and on July 10, 1989, act 793 was passed, and the bridge was renamed the Louisiana Airborne Memorial Bridge.
There is a visitors center at mile marker 121 (La. 3177), with 18 wheeler parking, and the Acadian chapter secured funding to erect a monument to the 82nd Airborne Division which was dedicated on October 20, 1990.
A September 2010, inspection showed the deck condition rating: satisfactory (6 out of 9), the superstructure condition rating: satisfactory (6 out of 9), the substructure condition rating: satisfactory (6 out of 9), and the sufficiency rating: 92.9 (out of 100)
