Everything for the I-10 Traveler

Louisiana’s New I-10 Bridge Receives Transportation Award

The Louisiana Department of Transportation and Development received an award by the American Association of State Highway and Transportation Officials (AASHTO) in the “under budget, large project” award category for completing the I-10 Twin Span Bridge under budget.

The new Twin Span Bridge, which crosses Lake Pontchartrain on Interstate 10 to link the cities of Slidell and New Orleans, was destroyed on August 29, 2005, by the storm surge from Hurricane Katrina.

Louisiana successfully let the first construction project to build a new Twin Span Bridge in April 2006 – less than 8 months after the original bridge was destroyed by Hurricane Katrina. The new bridge, which was completed in September 2011, is taller, wider and more robust than its four-lane predecessor. The new six-lane bridge has already helped to relieve congestion, improve mobility and enhance safety for the more than 55,000 drivers who make a daily trip across Lake Pontchartrain.

The project was completed for a total of $733 million – nine percent lower than its original estimated budget of $803 million. The Federal Highway Administration provided total funding for the effort because I-10 is a critical national corridor.
