Long-Allen Bridge

The Long-Allen Bridge is a K-truss steel structure that spans the Atchafalaya River, connecting the communities of Berwick and Morgan City in Louisiana. The structure has two traffic lanes and a design that allows river vessels to pass beneath it.

Built by Ohio-based Mt. Vernon Bridge Company, it opened in 1933 and served as a crossing on the Old Spanish Trail route. The structure represented an important infrastructure development for the region in the early twentieth century.

The bridge carries the names of two former Louisiana governors, showing how the state honors political figures through infrastructure projects.

Visitors can cross the bridge by car between the two communities, as it is designed for regular vehicle traffic. The crossing takes just a few minutes and offers views of the river and surrounding wetland landscape.

The bridge's main span was specially designed to provide adequate clearance for larger river ferries and commercial vessels traveling the waterway. This was a crucial requirement during planning because the Atchafalaya River remained an active commercial route for the region.
