Location

The Liberty Bridge, which was 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 (the Crosstown Boulevard) at its northern terminus.

It was designed by George S. Richardson and cost $3,456,000 to build.

History

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

It was designed by George S. Richardson and cost $3,456,000 to build. It is 2663' 3/16" long, though the main span is 448' and the water clearance is 44.4'.

It was renovated in 1982 by the Dick Corporation, at a cost of $32 million.

On September 2, 2016, the Liberty Bridge was closed for 24 days, following a fire during construction work on the bridge. Intense heat from burning plastic piping had caused a 30-foot (9 m) steel beam (compression chord) to buckle. The bridge reopened to weight-limited traffic on September 26, and full traffic on September 30. The Pennsylvania Department of Transportation assessed the value of the damages at over $3 million.
