Replacement of Caminada Bay Bridge in Louisiana Coastal Engineering Study and Support for Design

The 0.8 mile Caminada Bay Bridge on LA 1, owned and operated by the Louisiana Department of Transportation and Development (LADOTD), is a critical structure connecting Grand Isle and Louisiana’s mainland. The bridge was in poor condition due to serious corrosion and was scheduled for replacement under the Federal Bridge Replace Program before Hurricane Katrina. As a result of Hurricane Katrina, the bridge experienced additional damages that required emergency repair prior to reopening the bridge to traffic. The bridge is now scheduled for reconstruction in the fall of 2008. To assist with the design, a coastal engineering study from Coast & Harbor Engineering was acquired by LADOTD to investigate the vulnerability of the bridge to wave impacts from extreme hurricane events. The study includes development of the design hurricane event, numerical modeling of hurricane propagation to the project site (bridge), storm surge analysis, and computation of hurricane wave forces on the bridge spans. This study is also a test drive of the American Association of State Highway and Transportation Officials (AASHTO) Guide Specification for Bridges Vulnerable to Coastal Storms.
