John James Audubon Bridge
|Client:||Louisiana Department of Transportation and Infrastructure|
|Location:||St. Francisville, LA|
Flatiron designed and built a new cable-stayed bridge across the Mississippi River. The bridge, to be formally called the John James Audubon Bridge, replaced the ferry system and connects St. Francisville with New Roads just north of Baton Rouge, Louisiana.
Work for the project included 12 miles of roadway approaches that tie the bridge into US 61 and Louisiana Route 10. The main cable-stayed span stretches 1,583 feet across the Mississippi River making it the longest cable-stayed bridge in North America. The project broke ground on May 11, 2006 and the bridge opened in 2011.
The bridge is part of Louisiana's Transportation Infrastructure Model for Economic Development (TIMED) Program, a $4 billion program to construct 16 transportation projects, including highway improvements, three major bridges, and New Orleans port and airport improvements.
