The TIMED (Transportation Infrastructure Model for Economic Development) Program is the single largest transportation program in state history. The $5 billion improvement program includes widening 536 miles of state highways to four lanes on 11 project corridors, widening and/or new construction on three major bridges and improvements to both the Port of New Orleans and Louis Armstrong New Orleans International Airport. The program is designed to enhance economic development in Louisiana through an investment in transportation projects.

The three major bridge components of the TIMED Program include:

• the new Mississippi River bridge, the John James Audubon Bridge, that will connect New Roads and St. Francisville and replace the existing ferry
• the widening of the Huey P. Long Bridge in New Orleans
• the Florida Avenue Bridge over the Industrial Canal in New Orleans
