    Truck Rollover Warning System Project at the Route 15/I-180/Route 220 Interchange, Lycoming County

    November 06, 2025

    Montoursville, PA – Motorists are advised that work will continue next week on the installation of a Truck Rollover Warning at the Route 15 / Interstate 180 / Route 220 interchange in the City of Williamsport, Lycoming County.

    Starting on Tuesday, November 11, 2025, the contractor, Bruce and Merrilees, will be preforming calibration testing for the Truck Rollover Warning System. Work will be performed between the Foy Avenue / High Street interchange (Exit 137) and the Route 15 / Interstate 180 / Route 220 interchange. Motorists can expect shoulder closures where work is being performed. Work will be performed Tuesday between the hours of 9:00 AM and 12:00 PM. 

    Motorists should be alert, slow down, watch for lane changes, and drive with caution through the work zone.

    Bruce-Merrilees Electric Company is the prime contractor for this $879,000 Truck Rollover Warning System. The project includes the installation of a Dynamic Curve Warning System designed to alert tractor trailer trucks approaching the Route 15 southbound curve when they are traveling over 45 MPH. Work on this project includes installation of two upstream facing radar detectors 2,000 feet in advance of the curve to monitor each lane of approaching vehicles. The system will trigger two downstream message boards to activate and provide a message and graphic to warn a speeding truck driver to slow down for the approaching curve ahead. The message board will be blacked out when not activated. Work on this project is anticipated to be completed in the fall 2025, weather permitting.
