The Highland Park Bridge is a truss bridge that carries vehicular traffic across the Allegheny River between the Pittsburgh neighborhood of Highland Park and the suburb of Aspinwall.

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.
