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 John James Audubon Bridge, the longest cable-stayed bridge in the Western Hemisphere when it was completed in 2011, connects New Roads and St. Francisville and replaces a ferry service. This project also included more than 12 miles of approach roads. The project was honored by Engineering News-Record as the Editor's Choice for best construction project in the nation in 2012.
- The widening of the Huey P. Long Bridge in New Orleans was opened to traffic in 2013. In 2012, the bridge was named a Historic Civil Engineering Landmark by the American Society of Civil Engineers (ASCE), one of 250 such designations in the entire world.
- The Florida Avenue Bridge over the Industrial Canal in New Orleans has been placed on hold pending further environmental and development review.
