Adapting Coastal Infrastructure to Sea Level Rise and Land Loss
This “mock-up” shows the existing Highway LA-1 and Leeville Bridge in coastal
Louisiana (on the right) with a planned new, elevated bridge that would retain functionality under
future, higher sea level conditions (center left). (Current sea level and sinking bridge are shown
here.) A 7-mile portion of the planned bridge has been completed and opened to traffic in
December 2011. (Figure source: Greater Lafourche Port Commission, reprinted with permission).
