Brownsville Bridge

The Brownsville Bridge, also known as the Intercounty Bridge and the West Brownsville Bridge, is a truss bridge that carries vehicular traffic across the Monongahela River between Brownsville, Pennsylvania and West Brownsville, Pennsylvania. Since the opening of the Lane Bane Bridge and highway project to carry much of the intercounty through traffic away from the main streets of downtown Brownsville in the early 1960s, another commonly heard name is Old Brownsville Bridge for the four high level viaduct.

The West Brownsville-Brownsville Bridge was completed in 1914 to replace an 1831 wooden structure that was ill-suited for the vehicular traffic that the National Road was beginning to carry, as motorized vehicle traffic began replacing animal powered transportation technologies. The famous federal route has crossed the river at this point since its inception, with ferry service in the early nineteenth century.
