Snowden Road in South Park — which follows a tunnel under the Mon-Fayette Expressway — will close between Piney Fork Road and Sheplar Drive beginning at 7 a.m. on Wednesday and around the clock through late August.
Workers are reconstructing the road and conducting slide repairs, according to PennDOT spokeswoman Nicole Haney.
Commuters south of the closure can follow a posted detour via:
• Piney Fork Road
• Gill Hall Road
• Old Clairton Road
• Clairton Boulevard
• Curry Hollow Road
• Cochran Mill Road.
Northbound commuters can follow the same roads in the opposite order.
Snowden Road primarily passes through a residential area. The road is also a short distance from South Park Senior High School and South Park Elementary Center.
Commuters can track the closure on 511PA, the state’s official traffic site.
