MIFFLINTOWN — The following schedule of maintenance activities in Juniata County the week of May 12:

Bridge Maintenance and Cleaning

• Route 75 at a bridge spanning the Narrows Branch of Tuscarora Creek between Blair Mills and Brick Church roads in Lack Township. Monday through Friday. This work takes place off the roadway with minimal, if any, traffic impact.

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.

Manual Patching

• Route 235 between Long Hill Road in Susquehanna Township and the Juniata-Snyder County line in Fayette Township. Monday, through Wednesday. Flaggers in the roadway will provide traffic control during daylight hours.

• Route 1003 (Tennis Park Road) between Route 35 and Mountain Road in Fayette Township. Friday, May 16;

• Route 1005 (Leonard Hill Road) between Route 35 and Vanormer Road in Fayette Township on Thursday.

Most permanent pothole patching is completed in the spring/summer when temperatures stay consistently above freezing. If maintenance crews were not repairing potholes, the road surface would break up further and require more expensive corrective measures.

Pipe Replacement and Cleaning

• Route 35 between McKinley Road in Tuscarora Township and Cider Press Road in Beale Township Monday through Friday.

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.

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