The Homestead Grays Bridge, also known as the High Level Bridge, was built in 1936 and spans the Monongahela River between Homestead Borough and the southernmost tip of Pittsburgh's Squirrel Hill neighborhood. It is notable as the first bridge to incorporate the Wichert Truss, which uses a quadrilateral shape over each support, into its design. This made the truss statically determinate, so that forces in the structural members could be calculated.
The bridge was dedicated on Saturday November 20, 1937, having cost the county of Allegheny $2.75 million to build and originally carried four highway lanes and two streetcar tracks of Pittsburgh Railways Company. It replaced the 1897 Brown's Bridge which was upstream and had linked Brown's Hill Rd on the north bank and Second Avenue between Ann Street and Amity Street, Homestead on the south bank.
