Highway 90 Bridge

The Highway 90 Bridge boat ramp provides access to the Mermentau River in Acadia Parish, located conveniently beneath the U.S. 90 overpass near Mermentau, Louisiana. This ramp was upgraded through a $575,000 Louisiana Department of Transportation and Development (DOTD) project that included replacement of the ramp structure, grading improvements, and base course work. The site is positioned on the left side of the road before the bridge, making it straightforward to locate and access.

This is a practical access point for kayakers, canoeists, and boaters looking to explore the Mermentau River. The ramp's renovation ensures modern launching conditions for small to medium-sized vessels. The site's location under the highway bridge provides some shelter from weather and is easily identifiable as a public access point. Before visiting, check with Louisiana Department of Wildlife and Fisheries for any current conditions, water levels, or seasonal restrictions on the Mermentau River.
