The Allegheny County Department of Public Works has announced rehabilitation of the Philip Murray Bridge (South 10th Street) will begin Monday, June 19.

This phase of the project includes replacement of bridge deck, painting, structural steel repairs, wrapping of the suspension cables and the installation of dehumidification system is expected to cost $20 million. The project will be done in several stages and is scheduled to be complete by December 2018. 

Stage 1A will begin this month and includes the following restrictions:

• Traffic on the bridge will be reduced to one lane in each direction;

• The inbound, or east sidewalk, will be closed;

• Turning lanes on Second Avenue will be restricted;

• Trucks/buses traveling inbound on Second Avenue will not be able to make a left onto the bridge and trucks/buses traveling inbound on the bridge will not be able to make a right onto Second Avenue. In both cases, traffic will be detoured using the Armstrong Tunnel;

• Vehicles traveling in the left lane through the Armstrong Tunnels from Forbes Avenue must turn left onto Second Avenue. Through traffic onto the bridge, and those making the right on Second Avenue, are to use the right lane.

This stage will be complete by early October 2017 which will eliminate the need for the truck detour, but all other restrictions will remain. In 2018, Stage 2 will begin which will close the bridge to all vehicles traveling outbound and the downstream sidewalk.

The Philip Murray Bridge was opened in 1933, is 1,275 feet in length and is the only conventional (parallel cable) suspension bridge in the Commonwealth of Pennsylvania. This rehabilitation project is being done in conjunction with funding from the Commonwealth of Pennsylvania and the Federal Highway Administration. The work is being done by American Bridge Company of Coraopolis.

Phase 1 included replacement of both sidewalks and new lighting and was completed in 2014.
