Northbound I-79 Weekend Local Lane Closure in Allegheny County

​Pittsburgh, PA - PennDOT District 11 is announcing the closure of a single northbound lane on I-79 and the on and off-ramps at the Route 51/Coraopolis/McKees Rocks (Exit 64) interchange as part of the I-79 "S-Bend" project in Kennedy, Robinson, and Neville townships, and Glenfield Borough, Allegheny County will occur Friday night, August 23 through Monday morning, August 26 weather permitting.

There will be a closure of the northbound I-79 LOCAL LANE for crews to conduct paving operations beginning at 7 p.m. Friday, August 23 continuously through 6 a.m. Monday, August 26. All northbound I-79 traffic will use the crossed over express lane (left-hand lane) while the local lane is closed.

Additionally, the ramps carrying traffic from northbound I-79 to Route 51/Coraopolis/McKees Rocks (Exit 64) and traffic from Route 51 to northbound I-79 will close to traffic to allow crews to conduct milling and paving operations. Both ramps will close to traffic around-the-clock beginning at 7 p.m. Friday, August 23 through 6 a.m. Monday, August 26.

These restrictions could be lifted earlier if work is completed sooner.
