Road Plans
5-Year Road Guide - 2023
In 2023, Gibson-Thomas Engineering prepared a Five-Year Paving Guide (PDF) to assist with planning each year's contracted road improvements. To determine each year's program, the paving guide is reviewed and revised, and adjustments are made based on efficiency, cost-effectiveness and other factors. The final program each year is published via the township website and magazine.
RoadBotics Condition Assessment - 2022
In 2022, South Fayette Township updated road condition data using RoadBotics, a Pittsburgh-based spin-off of the Robotics Institute at Carnegie Mellon University.
Using artificial intelligence to analyze video footage of streets, RoadBotics rated roads from 1 (best condition - green) to 5 (worst condition - red). Overall, the entire road network was scored at 2.06.
Transportation Capital Improvement Plan - 2019
In 2019, engineers completed a Transportation Capital Improvement Plan (PDF) update so the township can collect transportation impact fees on new development.
Roadway Maintenance Plan - 2015
In November 2015, engineers completed a comprehensive Roadway Maintenance Study (PDF) of all township-owned roads.
The analysis detailed the need for $32 million in road improvements and prioritized the work. In 2015, the township established a dedicated annual funding stream for road work of at least $1 million a year.

Neighborhood Traffic Calming Policy & Procedures
The Neighborhood Traffic Management Program (PDF) establishes a process by which residents can submit requests for traffic calming improvements on local roads within South Fayette Township.
The township and/or the township traffic engineer evaluates each request. A plan may be implemented if resources are available and the request meets certain criteria.
Traffic Lights
South Fayette Township has been awarded more than $458,000 in Green Light-Go grant funds from the Pennsylvania Department of Transportation to help upgrade and install adaptive traffic signals aimed at improving traffic flow and reducing congestion in the area of Washington Pike, Route 50 and Interstate 79.
The system, including traffic lights and software, automatically adjusts signal timing based on traffic conditions. Upgrades include the following 10 intersections (nine in South Fayette and one in neighboring Bridgeville):
- Route 50 & Millers Run Road
- Route 50 & Municipal Drive/Newbury Drive (UPMC Children's & Newbury Market entrances)
- Route 50 & Hickory Grade Road
- Route 50 & southbound Interstate 79 ramps
- Route 50 & northbound Interstate 79 ramps
- Route 50 & Washington Pike (T-intersection at Starbucks and Chipotle)
- Washington Pike & Daniell Drive (near King's Restaurant and Get Go)
- Washington Avenue & Chartiers Street (across the Chartiers Creek bridge in Bridgeville)
- Washington Pike & Bursca Drive
- Washington Pike & Twin Ponds Lane
Chartiers Bridge Widening Project
As business development heated up around Interstate 79, Route 50 and Washington Pike, South Fayette Township worked toward a plan for comprehensive road improvements aimed at easing traffic flow for decades to come.
South Fayette created the Traffic Task Force along with local commercial developers, the municipalities of Bridgeville, Upper St. Clair and Collier, and officials from the state and Allegheny County. The group worked with the Pennsylvania Department of Transportation (PennDOT) and studied the best ways to construct and fund road improvements so traffic can move more smoothly on Route 50 and Washington Pike, which are state-owned roads.
Route 50 / Washington Pike / Chartiers St. / I-79
Based on input from the local Traffic Task Force, PennDOT widened the Chartiers Bridge from 4 lanes to 7 lanes and made other improvements in the area. The bulk of work wrapped up in June 2023.
Work included:
- Adding one lane to Chartiers Street (at Washington Pike)
- Adding one lane to the Interstate 79 northbound on-ramp in South Fayette
- Widening the bridge over Chartiers Creek (on Washington Pike between South Fayette Township and Bridgeville Borough) from 4 lanes to 7 lanes:
- Toward Bridgeville:
- Straight - two lanes
- One dedicated right-turn lane onto Chartiers Street
- From Bridgeville:
- Right turn from bridge to I-79 northbound ramp
- Right turn from bridge to I-79/Millers Run Road
- Straight to continue on Washington Pike
- Left turn into The Crossings at South Fayette shopping center (Aldi, Starbucks etc.)
