LOCK HAVEN — The Pennsylvania Department of Transportation (PennDOT) announced the following schedule of maintenance activities in Clinton County the week of Sept. 15. PennDOT performs year-round maintenance in its mission to provide a safe, efficient transportation system, and the scope of work in Clinton County for the coming week is as follows:

Bridge Maintenance & Cleaning

— Route 220 northbound at a bridge spanning the West Branch of the Susquehanna River one mile east of McElhattan in Pine Creek Township. Monday, Sept. 15, through Wednesday, Sept. 17. PennDOT will implement single-lane closures while this work is completed.

— Route 150 at the Constitution Bridge spanning the West Branch of the Susquehanna River in the City of Lock Haven. Wednesday, Sept. 17, through Friday, Sept. 19. Flaggers in the roadway will provide traffic control during daylight hours.

Pennsylvania has some of the oldest bridges in the country, with an age of more than 50 years on average. Preventive maintenance is vital in extending the life of the structures. As such, PennDOT maintenance crews perform some bridge deck patching and structural repairs.

Crack Seal & Hot Pour Mastic

— Interstate 80 between mile markers 185 and 194. Monday, Sept. 15, through Friday, Sept. 19. PennDOT will implement single-lane closures while this work is completed.

Crack sealing and hot pour mastic operations prevent water intrusion from seeping through cracks or joints in an asphalt road, which can lead to potholes and pavement breakup. They are proactive preventive maintenance strategies to prevent water from entering the roadways and accelerating the formation of potholes and other failures.

Shoulder Maintenance

— Route 120 between Kettle Creek and Gratzmar Avenue Road in Noyes Township. Monday, Sept. 15, through Friday, Sept. 19. Flaggers in the roadway will provide traffic control during daylight hours.

Shoulder cutting removes excess material and debris from unpaved shoulder areas. Shoulder grading involves the shaping and stabilizing of those same areas. Both operations improve drainage, allow water to leave the roadway, and eliminate shoulder drop-offs. These are crucial highway maintenance operations because when drainage systems do not function properly, water collects on the road, weakens pavement, accelerates the formation of potholes, and creates the potential for icing conditions in the winter months.

Vegetation Management

— Route 120 between Route 4002 (Keating Road) in East Keating Township and Rio Vista Lane in Chapman Township. Monday, Sept. 15, through Friday, Sept. 19. This work takes place off the roadway and has little, if any, traffic impact.

— Route 477 between Route 64 and the Centre-Clinton County line in Lamar Township. Monday, Sept. 15, through Friday, Sept. 19. This work takes place off the roadway and has little, if any, traffic impact.

Mowing, herbicide spraying, and selected tree thinning help maintain a safe roadway free of obstructing vegetation, improving visibility to spot signage, traffic control devices, and other motorists, bicyclists, pedestrians, and animals approaching the road. Additionally, a well-maintained roadside can improve drainage and prolong the life of the roadway.

This schedule is subject to change due to weather conditions, emergencies, or other unforeseen interruptions.
