PITTSBURGH – The Allegheny County Department of Public Works today announced that traffic on the Mansfield Bridge, which spans the Monongahela River between Dravosburg and McKeesport, will be restricted to the center lanes (one lane in each direction) beginning at 9:00 a.m. on Monday, March 19, and continuing until 6:00 p.m. on Thursday, March 22. At that time, traffic will be routed to the upstream side of the bridge with a single lane in each direction maintained at all times.

There will be no closures of the bridge. However, motorists are advised that minor delays may occur as a result of the new traffic patterns. Temporary traffic signals will also be in operation at the approaches to the bridge due to the new traffic patterns and cross-traffic that will occur in the work zone.

These restrictions are necessary for the $31 million rehabilitation of the 1400’ thru-truss bridge. The project includes replacement of the entire bridge deck, repair of deteriorating concrete on the substructure, addition of scour protection on the river piers, cleaning and repainting the superstructure, installation of new hand railing along the entire length of the structure, and replacement of bridge, roadway and navigational lighting systems. Concrete repair and paving will be done on the ramps leading to McKeesport and Glassport. West Fifth Avenue will be paved from McKeesport to Glassport. Work will also be done on the ramps that connect the bridge to Maple Avenue in Dravosburg. Overall completion of the project is scheduled for fall 2014.

The county has created a Mansfield Bridge Project website with construction details and traffic information at Mansfield Bridge Project.
