​​​​​Route 401 and Valley Hill Road Intersection ​Improvements

​

Project Location

​

Overview​

This project will improve the intersection of Route 401 (Conestoga Road) at the Valley Hill Road Intersection in Charlestown Township, which experiences significant congestion during peak hours. During peak hours, significant queues develop on Route 401 (Conestoga Road). Traffic volumes exceed the current capacity of the intersection as presently configured. The addition of turn lanes for Route 401 (Conestoga Road) would eliminate much of this backup. Presently, when vehicles are waiting to make a left turn in either the northbound or southbound direction on Route 401 (Conestoga Road), through movements are impeded and backups occur. This project is located approximately a half mile from the PA Turnpike and approximately two miles north of U.S. 202.

The proposed improvements include adding left turn lanes on Route 401 (Conestoga Road) for both eastbound and westbound traffic, replacing existing traffic signal equipment, and updating signal timing patterns to allow for left turn-only movements for both eastbound and westbound traffic. In addition, the project includes minor shoulder widening and stormwater improvements. The project will be constructed utilizing temporary lane and shoulder closures as well as detouring of Valley Hill Road.​
