PennDOT schedules Route 66 reconstruction and safety upgrades through Delmont

PennDOT has scheduled a major Route 66 preservation and safety project for a proposed construction window running from summer 2026 through fall 2027. The work will cover about 9.5 miles across Delmont Borough, Murrysville, Salem Township and Washington Township.

The Pennsylvania Department of Transportation updated its Route 66 Pavement Preservation project page July 8, 2026. The project is expected to bring extended road and intersection changes while improving pavement, traffic control, pedestrian access and safety along the corridor.

What the project includes

Route 66 will be milled and resurfaced within the project limits. PennDOT also plans to replace traffic signals at Route 66 and Manor Road and at Route 66 and Pittsburgh Street.

ADA ramps will be replaced as part of the work. On the west side of Route 66, crews will install new sidewalk, sidewalk lighting and landscaping between Stotler Road and Pittsburgh Street.

The project also calls for reconstruction of the Route 66 northbound lanes between Zubal Road and Beaver Run Road. That work is separate from the broader resurfacing planned along the route and targets a specific section of the northbound roadway.

At Route 66 and Route 356, the intersection will be reconfigured as a T-intersection controlled by a new traffic signal. The redesign is intended to change how traffic moves through one of the project’s named intersections.

What residents and drivers should expect

Because the construction window extends into fall 2027, people traveling through Delmont and the neighboring municipalities should expect the project to continue over multiple seasons. The work will affect roadway surfaces, signals, lanes, sidewalks and intersections rather than being limited to a single resurfacing operation.

PennDOT’s project information does not provide a detailed day-by-day traffic-control schedule. Specific lane restrictions, closures and traffic patterns may therefore be announced as construction advances. The proposed fall 2027 end date can also change because of weather, contracting and field conditions.

The project’s transportation-program records identify it as PennDOT project 116179 and list the approximate length at 9.50 miles. Delmont Borough’s agenda and meeting-minutes page lists a July 8, 2026 borough council agenda and remains a municipal channel for local public notices during the project period.

For Delmont, the planned improvements combine road reconstruction with pedestrian and signal upgrades. The work is expected to create a prolonged period of construction changes, but its stated purpose is to improve the condition and safety of Route 66 for drivers and people walking along the corridor.
