History
The bridge was built in 1890 by the Western Pennsylvania Railroad (West Penn) to gain access to Herr's Island. It left the main line on the mainland by means of a curving red brick viaduct and three plate girder spans over River Avenue and the B&O before crossing the back channel on a Whipple truss to reach the stockyards and warehouses on the island. In 1903, the West Penn was purchased by the Pennsylvania Railroad, becoming the Western Penn branch. The bridge was strengthened and raised later in the same year to match the raised land level on the island.
Between 1970 and 1990, the brick viaduct and three plate girder spans were removed. In 1999, about a decade after the redevelopment of the island with condominiums and a business park, the bridge was re-decked and reopened as part of the Three Rivers Heritage Trail.
