PennDOT is currently performing preliminary engineering for the Route 15 Section 044 Reconstruction Project. The project is four miles in length between the Range End Road/Golf Course Road intersection in Carroll Township, York County and continues north through Dillsburg Borough before crossing into Upper Allen Township, Cumberland County and ending north of the Glenn Bowers Memorial Bridge carrying Route 15 over the Yellow Breeches Creek. 

The primary proposed improvement includes the full-depth reconstruction of existing Route 15 from the southern project limit north to approximately 600’ south of the Glenn Bowers Memorial Bridge, with the remaining portion of existing roadway being milled and overlaid to the southern end of the bridge.  The project also includes bridge preservation improvements of the existing Glenn Bowers Memorial Bridge.  Turn lane lengths are being updated to provide adequate storage length, as well as the addition of a third right turn auxiliary lane throughout the majority of the project corridor south of the Ore Bank Road/Spring Lane Road intersection.  Additional improvements include updates to existing drainage systems, stormwater facilities, guide rail, upgrade/replacement of existing traffic signals at the four signalized intersections, review of pedestrian accommodations at the four signalized intersections, and reduction of unrestricted access to businesses along the corridor.  

Construction activities for the Route 15 (Blue & Gray Highway) Reconstruction project will be staged to minimize disruptions to traffic and maintain access for residents, businesses, and emergency services. Two eleven-foot lanes of Route 15 traffic are anticipated to be maintained in each direction during staged construction except during short-term, off-peak operations. Certain turn movements may possibly need to be detoured at various stages of construction. Business access will be maintained at all times during business hours. Coordination will be ongoing with local municipalities, businesses and emergency responders to ensure continued access and responsiveness throughout all construction phases. 

The project is currently in the preliminary engineering phase and physical work is anticipated to take place between the 2028 and 2031 construction seasons, subject to all approvals, environmental clearances, and funding availability.
