ABOUT THE PROJECT
U.S. Route 22 Bridges
State Route 576, Section 55A1-1: Adjacent to (East of) the previously completed State Route 576. This interchange is located approximately 5 miles Southeast of the Pittsburgh International Airport and carries State Route 576 over U.S. Route 22. The mainline twin structures each consist of a 4-span steel multi-girder bridge that span State Route 4004 and U.S. Route 22 along with ramps for the previously constructed Southern Beltway. This section required 200,000 cubic yards of excavation. The bridges are approximately 800 feet in length.
