The Pennsylvania Department of Transportation is progressing with plans to upgrade the Kennett-Oxford Bypass, a 22.5-mile limited access highway identified as U.S. 1. This route stretches from the Pennsylvania-Maryland border in West Nottingham Township to Schoolhouse Road in East Marlborough Township, located in Chester County.
The proposed enhancements to the roadway involve a complete reconstruction of the existing pavement, minor widening of the shoulders, replacement of guide rails, improvements to drainage systems, and the establishment of new stormwater management facilities. In addition, significant work is planned for bridges, including the rehabilitation or replacement of sixteen mainline bridges, nineteen overpass bridges, and seven culverts situated along the corridor. Adjustments to the elevation of the mainline pavement or the intersecting roads at each overpass will ensure that the necessary vertical clearance over the bypass is maintained.
Traffic operations are also set to be enhanced through various means, including the lengthening of acceleration and deceleration lanes at entrance and exit ramps, refining intersection controls at ramp terminal intersections, and implementing intelligent transportation systems, which may comprise CCTV cameras and Dynamic Message Signs for improved traffic management.
Furthermore, the approach roadways at intersecting roads—such as Sylmar Rd, Ridge Rd, PA 272, PA 472, PA 10, PA 896, PA 796, PA 841, PA 41, Newark Rd, and PA 82—are slated for enhancements to incorporate turning lanes and profile adjustments at interchanges. The ongoing study of ramp terminal intersections also aims to explore better control measures, including the potential installation of new traffic signals or roundabouts. Specifically, the intersections at Chatham Road (PA 841) and E. Evergreen St, as well as E. Evergreen St (PA 841) and Oakland Ave in West Grove Borough, are under review for improvements as part of this initiative.
Importantly, these projects will work in tandem with local trail initiatives, and certain locations may see upgrades to trail systems as outlined in Chester County’s Southern Chester County Circuit Trail Feasibility Study.
The entire corridor is being divided into four distinct sections to facilitate the design and construction phases.
This substantial investment in infrastructure is not only set to promote safer and more efficient travel but also aims to enhance local connectivity and support future growth in the region. By addressing both roadway and pedestrian needs, the project reflects a broader commitment to community development and environmental stewardship.
