The first highway bridge between Bon Weir, Texas and Merryville, Louisiana was constructed by the Austin Bridge Co. in 1930-31. The cost of $180,000 was split three ways between the federal government and the states of Texas and Louisiana. The bridge was formally opened on July 4, 1931 and was referred to in its early years as the Bon Weir Bridge.

The bridge became part of US 190 when that route was extended west from Baton Rouge, Louisiana over existing state highways in the summer of 1935.

It was replaced with the current bridge, constructed immediately to the south, in 1981.
