A section of Greensburg Pike near Great Valley Shopping Center in North Versailles Twp. will close next week and remain closed until mid-August.
A spokeswoman for the Allegheny County Department of Public Works said the closure, which begins at 7 a.m. April 18, is necessary to stabilize the road. A reinforced retaining wall built of "geo-grid" will be used.
The closure will affect the area behind the Save-a-Lot store.
The posted detour will use Route 30 and Warren Drive. The $590,000 project is being completed by A. Merante Contracting Inc. of West Mifflin.
