LOCK HAVEN — The Pennsylvania Department of Transportation (PennDOT) announced the following schedule of maintenance activities in Clinton County this week.

PennDOT performs year-round maintenance in its mission to provide a safe, efficient transportation system, and while crews will be off on Monday, Sept. 1, in observance of Labor Day, the scope of work in Clinton County for the remainder of the week is as follows:

Bridge Maintenance & Cleaning

— Route 220 at various bridges between mile markers 109 and 115. Thursday, Sept. 4, and Friday, Sept. 5. PennDOT will implement single-lane closures while this work is completed.

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.

Pipe Replacing & Cleaning

— Route 4001 (Kettle Creek Road) between Whiskey Springs Road in Noyes Township and Route 144 in Leidy Township. Tuesday, Sept. 2, and Wednesday, Sept. 3. Flaggers in the roadway will provide traffic control during daylight hours.

Pipe replacement and cleaning are essential in maintaining water flow around state roadways. Controlling water flow is one of the most important aspects of maintaining pavements. Uncontrolled water flow will damage both the pavement surface and the area under the pavement, which causes deterioration across the length of the pipe.

Shoulder Maintenance

— Route 2020 (Lusk Run Road/Hill Street) between Route 150 in Bald Eagle Township and Oak Lane, the City of Lock Haven. Tuesday, Sept. 2, through Friday, Sept. 5. 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.

Side Dozing

— Route 880 between the Centre-Clinton County line in Logan Township and Wolfe Road in Crawford Township. Tuesday, Sept. 2, through Friday, Sept. 5. Flaggers in the roadway will provide traffic control during daylight hours.

Side dozing removes excess material from beneath guide rail areas, which improves drainage and allows water to sheet flow off the roadway. Side dozing is a crucial highway maintenance operation 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

— Interstate 80 between mile markers 170 and 194. Tuesday, Sept. 2, through Friday, Sept. 5. This work takes place off the roadway and has little, if any, traffic impact.

— Route 2002 (Washington Avenue/Winter Road/Narrow Road/Teach Springs Road) between Route 64 in Porter Township and Route 880 in Logan Township. Tuesday, Sept. 2, through Friday, Sept. 5. PennDOT equipment will be in the roadway for this continuously moving operation that drivers may pass via the open lane providing they do so cautiously and in the absence of oncoming traffic in the opposing lane.

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.

Customers can report road concerns by calling 1-800-FIX-ROAD. If calling after hours, please leave a name and phone number.
