Last Updated: 08/07/2025

Study Underway:

The Pennsylvania Department of Transportation (PennDOT), Fayette County, and Greene County, in cooperation with the Federal Highway Administration (FHWA), will complete an in-depth study for the development and analysis of possible concepts to meet Pennsylvania Route 21 (PA 21) corridors purpose and needs; and to develop design strategies to improve safety and mobility on the transportation network. 

The project limits begin on Route 21 at the intersection of Route 19 in Morrisville, Greene County and proceeds east on Route 21 approximately 25 miles to the intersection of Route 40 in Uniontown, Fayette County.

The purpose of this effort is to consider safety updates to meet current traffic conditions. Work will include, but is not limited to:

• Reviewing existing data, environmental features, and geotechnical conditions 
• Collecting additional traffic counts and crash data where needed along the transportation network
• Conducting origin and destination surveys to determine existing traffic patterns
• Evaluating the existing corridor transportation network to determine strategies to improve safety, mobility, and reliability 
• Establishing a public involvement process, including a Project Advisory Committee (PAC), to gather ideas, concerns, and input from stakeholders and the communities within the corridor
• Holding community outreach sessions
  

Studies for the project began on August 21, 2024. The design team is being led by Sucevic, Piccolomini and Kuchar, Engineering Inc. (SPK) from Uniontown, PA.

Project Update: 

On Wednesday, May 14, 2025, the first Project Advisory Committee (PAC) Meeting was conducted by The Pennsylvania Department of Transportation (PennDOT), in cooperation with the Federal Highway Administration (FHWA).  The PAC Meeting was held at the PennDOT Greene County Maintenance Office located at 129 Jefferson Road, Waynesburg, PA 15370.  Thirteen (13) project team members attended to collaborate with thirty-one (31) Project Advisory Committee (PAC) members.  The PAC members included elected officials, emergency services, police, first responders, school districts, and local planners. (The meeting was invitation-only and was not open to the public)

The meeting format began with a meet n’ greet showcasing large scale plans of the project scope area to gather input on existing conditions and areas of concern and interest. PennDOT District 12 and the project team then presented a PowerPoint that included:

• Purpose and Need
• History of the Corridor
• Traffic and Safety Data
• General Safety Concerns
• Top 3 Locations – Specific Priorities
• Next Steps

The next steps will include finishing the initial studies, establishing the project purpose and need document, exploring alternatives and considering improvement projects.

A public meeting is anticipated to be held in 2026.
