U.S. Route 22 in Westmoreland County is proposed to be reconstructed as part of the Renew 22 Project from the Allegheny/Westmoreland County Line east to the Westmoreland/Indiana County Line. The Route 22 project area is located within the Municipality of Murrysville, Salem Township, Borough of New Alexandria and Derry Township.

Route 22 is part of the National Highway System and as such is recognized as a vital link in Pennsylvania's transportation network. Locally, Route 22 serves as the area's primary east/west highway. Regionally, Route 22 provides a convenient link from the Pittsburgh metropolitan area to central Pennsylvania (i.e., Indiana, Altoona, Johnstown, State College). Access from this portion of U.S. Route 22 are provided to I-376, I-76, State Route (S.R.) 286, S.R. 0066/Amos K. Hutchinson Expressway, U.S. Route 119, U.S. Route 219 and U.S. Route 220/I-99.

The existing Route 22 is a varying combination of two lanes to four lanes for the highway. Several portions of this approximately 23 miles of Route 22, have been recently reconstructed to provide widening to four lanes (two in each direction) and a median with a barrier in the center. Access is provided at key intersections and crossing movements are limited to these locations. The remaining portions of U.S. Route 22 in Westmoreland County are planned to be reconstructed similarly to the completed sections and are scheduled for completion of construction by the end of 2006.

Specific details concerning the proposed series of construction sections of Route 22 in Westmoreland County are described within each respective section of this webpage, including: Section B01; Section B02; Section B08; Section B09; Section B10.
