The document summarizes bridge data from Louisiana's 2013 National Bridge Inventory. It finds that 14% of the state's 13,050 bridges are structurally deficient, and 15% are functionally obsolete. Between 2003-2012, $2.5 billion in federal funding supported bridge construction and rehabilitation projects on over 2,300 bridges. The state estimates it would cost $4.6 billion to repair 3,416 bridges. The top 10 most traveled structurally deficient bridges and their locations are also listed.
