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.

[1] 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.
