Nightly lane closures are set to begin Sunday and last throughout the week near the Route 51/Route 88 intersection as crews perform drilling operations as they design future improvements in the area.
PennDOT District 11 officials said there will be short term lane closures on Route 51, Route 88 and Provost Road in Whitehall Borough and Pittsburgh's Overbrook section. Restrictions will occur nightly, Sunday through Thursday, from 8 p.m. to 6 a.m.
Outlined restrictions include:*Sunday and Monday, July 10 and 11: lane closures on Route 51 southbound.
*Tuesday, July 12: lane closures on eastbound Route 88.
*Wednesday, July 13: lane closures on Provost Road at the Route 51 intersection.
*Thursday, July 14: lane closures on northbound Route 51.
Delays are expected, PennDOT officials said.
Construction for the $14 million improvement project for the Route 51/Route 88 intersection in the Overbrook section of Pittsburgh and Whitehall Borough is set to begin in 2013 and be completed in 2014.
The project includes the replacement of six bridges along the corridor that have been deemed "structurally deficient," officials have said. Emergency repairs already have been made on some of the structures.
Plans are for a "jug handle," or ramp-like structure, to be built on the northbound side of the state route to direct traffic around the area — going behind the Rite Aid Pharmacy and intersecting with Route 51, where Ivyglen Street sits.
PennDOT officials have said they estimate the project will result in a 50 to 60 percent reduction in traffic delays at the Route 51 and Route 88 intersection.
