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 through Sunday, September 6-8 weather permitting.
Beginning at 7 p.m. Friday, September 6 through 12 p.m. Sunday, September 8 there will be a closure of the crossed over northbound I-79 EXPRESS LANE for crews to allow crews to remove the I-79 northbound crossover. Crews will conduct barrier removal and line painting operations to restore northbound traffic to its original configuration. All northbound I-79 traffic will use the local lane (right-hand lane) until the northbound configuration is restored.
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 line painting operations. Both ramps will close to traffic around-the-clock beginning at 7 p.m. Friday, September 6 through 7 p.m. Saturday, September 7. Ramp traffic will be detoured.
All restrictions could be lifted earlier if the work is completed sooner. Please use caution when traveling through the work zone.
