The Fort Pitt Tunnel carries Interstate 376 (Interstate 279 prior to June 10, 2009), US 22, US 30, and US 19 Truck between Downtown Pittsburgh and its West End neighborhood in the U.S. state of Pennsylvania. It has two lanes both inbound and outbound. The tunnel travels beneath Mount Washington. Its northern ramps lead directly to the double-deck Fort Pitt Bridge. To mesh with the bridge, the North portal has openings at two levels, with the eastern opening leading to the top deck of the bridge. At the South portal the openings are at the same level.
