WARWICK TWP, PA — Drivers and visitors heading to the historic St. Peters Village area can once again travel through St. Peters Road after PennDOT reopened the roadway one month ahead of schedule following a major retaining wall project in northern Chester County.
At a Glance
- Roads Affected: St. Peters Road within the St. Peters Village Historic District
- Dates: Road reopened Monday
- Times: Roadway fully reopened to traffic
- Reason: Completion of retaining wall and slope stabilization project
According to the Pennsylvania Department of Transportation, the emergency infrastructure project addressed years of erosion and slope instability along the steep embankment between St. Peters Road and French Creek.
State officials said the deteriorating hillside had compromised the roadway’s guiderail system and created unsafe conditions for motorists traveling through the popular historic destination.
In 2022, PennDOT installed a concrete barrier to shield drivers from worsening slope conditions. Additional inspections later found continued erosion, requiring another 432 feet of concrete barrier and a long-term detour through the area.
PennDOT began designing a permanent solution in July 2024, but worsening slope failure led the department to issue an emergency proclamation in April 2025 to accelerate repairs and stabilize the roadway.
The completed project included construction of a 570-foot retaining wall designed to protect the roadway embankment and improve long-term safety through the corridor.
PennDOT Secretary Mike Carroll noted that the work helps preserve safe access to one of Chester County’s best-known historic destinations, which attracts thousands of visitors each year.
The $6.8 million design-build project was completed by Loftus Construction and funded entirely through state dollars.
Although the roadway has reopened, motorists are still encouraged to use caution when traveling through the narrow historic corridor and remain alert for any remaining construction activity or roadside work.
