CNR Bonnet Carré Spillway-McComb Bridge

CNR Bonnet Carré Spillway-McComb Bridge is a railroad bridge that spans across the Bonnet Carré Spillway and part of Lake Pontchartrain in Louisiana. It carries both Amtrak passenger trains and Canadian National Railway freight trains on the same tracks.

The wooden trestle bridge opened in 1936 as a critical transportation link for the Canadian National Railway in the southeastern United States. It became an important route for connecting different regions of Louisiana by rail.

The bridge represents an engineering milestone in Louisiana's rail infrastructure, documented in the Historic American Engineering Record for future generations.

Trains use this bridge regularly, so you may see them passing through if you visit during active train hours. The best viewing spots are from the spillway banks or nearby roads that offer clear views of the structure.

A fire in 2016 damaged a significant section of the wooden structure, but repairs were completed within a week. This rapid restoration showed how critical this rail connection was to operations.
