The Long–Allen Bridge was a truss bridge carrying Highway 8 across the Ouachita River at Harrisonburg in Catahoula Parish, Louisiana. This was the only point where La Route 8 crossed the Ouachita River in Louisiana. It was originally constructed in 1932, and it carried approximately 3,000 vehicles per day.

The structure was considered to be in "poor standing" by the Louisiana Department of Transportation and Development. In August 2017, a replacement span named the Veterans Memorial Bridge was opened. As of November 2017, the bridge was no longer in commission, and in January 2018, the bridge was demolished.
