422 Improvements

​Program Overview:

PennDOT's comprehensive, multi-phase U.S. 422 Improvement Program spans more than 20 miles from U.S. 202 in King of Prussia to the Montgomery County/Berks County line.  

Since 2012, PennDOT has completed six major projects and invested $263.4 million to reconstruct and improve the U.S. 422 corridor in Montgomery and Chester counties. 

Two new U.S. 422 projects will move into construction in 2023, including Section MCP, which is located in Upper Providence and Lower Providence townships, Montgomery County, and Section M1B, which is located in Lower Pottsgrove Township, Montgomery County.
