King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that a section of southbound St. Peters Road within St. Peters Village will be closed and detoured in Warwick Township, Chester County, beginning Thursday, May 22, due to additional slope deterioration between the roadway and French Creek.
A PennDOT project to construct a retaining wall along St. Peters Road to stabilize and restore the southbound lane is expected to begin this fall and finish in spring 2026.
Beginning Thursday, May 22, southbound St. Peters Road will be closed and detoured to through traffic between School Road and Rock Run Road.
During the closure, passenger vehicles will be directed to turn left onto School Road, turn right onto Harmonyville Road, turn right onto Chestnut Hill Road, turn left onto Old Ridge Road, turn right onto Coventryville Road, and turn right onto Route 23 (Ridge Road) to access St. Peters Road.
Truck traffic will be directed to turn left onto School Road, turn right onto Harmonyville Road, turn left onto Laurelwood Road, turn right onto Cedarville Road, turn right onto southbound Route 100 (Pottstown Pike), and turn right onto Route 23 (Ridge Road) to access St. Peters Road.
Local access will be maintained at all times for St. Peters Road residences and businesses.
Motorists are advised to allow extra time when traveling near the work area because backups and delays may occur.
