The Fort Pitt Bridge is a steel, double decker bowstring arch bridge that spans the Monongahela River near its confluence with the Allegheny River in Pittsburgh, Pennsylvania. It carries Interstate 376 between the Fort Pitt Tunnel and Downtown Pittsburgh. It was the world's first computer designed bowstring arch bridge and double-decked bowstring arch bridge. The bridge is known for its difficult lane changes, especially on the lower level, often requiring people to go from the extreme left lane across two lanes to the extreme right lane in only 300 feet. The upper level is more forgiving for some routes, but still requires a full span lane change in 300 feet to get from the south side entrance to the downtown exits.


The $6.305 million Fort Pitt Bridge, designed by George S. Richardson of Richardson, Gordon, & Associates, opened at 11 a.m. on June 19, 1959 with a ribbon-cutting ceremony by Gov. David L. Lawrence before a caravan, including Mayor Thomas Gallagher and mayoral candidate Joseph M. Barr, was driven across while a city fireboat gave a hose salute upriver. Its two predecessor bridges, the original Point Bridge (1877-1924) and its replacement of the same name (aka Point Bridge II, 1927-1959), spanned even closer to the aforementioned confluence from West Carson Street (near the Duquesne Incline) to Water St. (now Fort Pitt Blvd.), near the tip of Point State Park. The Point Bridge closed two days after the opening of the Fort Pitt Bridge, but remained standing until it was dismantled (along with the connected Manchester Bridge) in 1970.
