The 1902 Highland Park Bridge was a cantilever through truss that carried two streetcar tracks across the Allegheny River and Sixmile Island between the Pittsburgh neighborhood of Highland Park and Sharpsburg, Pennsylvania. It was replaced by the Highland Park Bridge in 1938.LocationThe bridge was in two sections, with the cantilever on the Pittsburgh side of Sixmile Island and a truss bridge on the Sharpsburg side. It was situated 400ft downstream from the 1938 Highland Park bridge, at the then downstream end of the island. However, contemporary maps and pictures imply that the island has moved almost its entire length downstream, making the bridge location the current (2010) upstream end of the island.
