PennDOT will resume work next week on upgrading signals and installing ramps throughout the City of Butler.

Starting Monday, March 30, crews will work to upgrade signals and install Americans with Disabilities Act-compliant ramps along Route 68 between the intersections of Hansen Avenue and Monroe Street, the department said. Work began last year and is expected to continue through December.

Single-lane restrictions will be implemented as needed between 7 a.m. and 5 p.m. Drivers should use caution and prepare for potential delays when passing through the area.
