The Horace Wilkinson Bridge is a cantilever bridge carrying Interstate 10 in Louisiana across the Mississippi River from Port Allen in West Baton Rouge Parish to Baton Rouge in East Baton Rouge Parish. Around the Baton Rouge Metropolitan Area, the bridge is more commonly known as the "New Bridge" because it is the younger of the two bridges that cross the river in Baton Rouge. The structure begins at the Louisiana Highway 1 (LA 1) exit south of Port Allen. After the interstate crosses the superstructure, it remains an elevated viaduct up to the Dalrymple Drive exit to Louisiana State University.
