Location

The Liberty Bridge, completed in 1928, connects downtown Pittsburgh, Pennsylvania to the Liberty Tunnels and the South Hills neighborhoods beyond. It crosses the Monongahela River and intersects Interstate 579 at its northern terminus.

History

Liberty Bridge was constructed as the missing link between downtown and Liberty Tunnel, which had been constructed four years earlier in 1924 as a link to the South Hills. It opened on March 27, 1928, following a 5-mile (8.0 km) vehicle parade^[1] from the southern suburbs of the city, which crossed Smithfield Street Bridge and proceeded through downtown before ending at the southern end of the new bridge.^[2]
