About $528 million in Southwestern Pa. roadwork detailed by PennDOT

About $528 million will be spent on more than 100 road projects across four Southwestern Pennsylvania counties this year, state transportation officials said Monday.

The work includes everything from reconfiguring a highway interchange in Rostraver to improving traffic signal features at nearly 50 intersections.

The projects represent a combined cost of about $528 million in federal and state funding for work in PennDOT District 12, which includes Westmoreland, Fayette, Washington and Greene counties.

Work to update and reshape the interchange at Interstate 70 and Route 51 has continued through two winters in Rostraver. When it’s done, it will be the second “diverging diamond” interchange in District 12, allowing drivers on Route 51 to make a left turn onto the interstate without making a potentially hazardous maneuver across an opposing lane of traffic.
