Project Overview


The US 422, Section 29M Reconstruction project involves the reconstruction and widening of approximately 5-miles of US 422 (West Shore Bypass) including the interchanges at N. Wyomissing Boulevard, Penn Street/Penn Avenue, Lancaster Avenue, and I-176.  The project extends through the City of Reading, West Reading Borough, Wyomissing Borough, Cumru Township, and Exeter Township in Berks County. Part of the National Highway System, the bypass was constructed in the late 1950s and early 1960s and provides an important link in the regional transportation network connecting to other key transportation arteries including US 222, I-176, PA Route 10, and PA Route 12. US 422 and these links provide a direct eastern connection from Reading to Pottstown, King of Prussia, and Philadelphia.

In 2014, PennDOT completed the Route 422 West Shore Bypass Reconstruction Study which identified transportation projects that will improve the safety, operations, regional mobility, and local access of the existing corridor. The current project builds on the study’s recommendations for the corridor between PA Route 12 and I-176, and advances them to further study, design and environmental clearance to construction.

The project is currently in the preliminary engineering stage, which develops the key design components such as alignments, profiles, lane/shoulder/median widths, interchange and traffic signal operations, and preliminary bridge sizing.  Critical project items such as roadway drainage, stormwater management, bridge hydraulics, traffic control, and constructability are all developed to a preliminary stage to assist in identifying potential impacts to adjacent properties, utilities, railroads, cultural resources, and environmental features.  Feedback from the public, public officials, and other stakeholders is also solicited during this phase to ensure the project meets the purpose and needs as well as the needs of the affected communities.  Adjustments to the design can be made during this phase in response to comments and suggestions received or to avoid, minimize, or address impacts and progress the project towards environmental clearance.
