Chacahoula Swamp Bridge

Chacahoula Swamp Bridge is a concrete trestle bridge stretching across wetlands in Louisiana, consisting of twin parallel structures. It carries US Route 90 and links several parishes in southeastern Louisiana.

The bridge was completed in 1995 by Louisiana Department of Transportation to improve connection between the eastern and western parts of the state. This infrastructure project helped address transportation needs in the region.

The bridge passes through areas where people fish using traditional methods and watch native animals in the wetlands below.

The bridge carries heavy commercial traffic and functions as a main transportation route in southeastern Louisiana. Drive carefully and allow extra time for potentially slower travel conditions on this main corridor.

This bridge ranks among the longest in the world, spanning vast swamp ecosystems home to many native species. From this height, travelers can see the expanse of the wetlands and understand the scale of the landscape below.
