Allegheny County is set to tear into Campbells Run Road on March 9, launching a $45.8 million overhaul that county leaders say is the Department of Public Works' largest project to date. The multiyear rebuild will reshape about 1.63 miles of roadway through Robinson and Collier townships and is expected to run through 2031. County officials say the work is designed to untangle chronic backups and finally fix the drainage issues that routinely snarl traffic and shut the corridor down after storms.
According to WPXI, the project will reconstruct Campbells Run Road between McMichael Road and Keiners Lane and add a two‑way center turn lane. Work will roll out in phases starting March 9, with periodic lane closures expected through the end of 2026. The Federal Highway Administration will cover about 80 percent of the cost, with Allegheny County paying the balance, and the full program is projected to continue through 2031.
What crews will build
The plan calls for widening the corridor to make room for a two‑way center turn lane, along with dedicated left‑ and right‑turn lanes at major intersections. It also adds bike sharrows and a sidewalk between Business Center Drive and Penn Center Boulevard. As outlined by SAI Consulting Engineers and highlighted in coverage from the West Hills Gazette, the work includes nine retaining walls, two stormwater basins, culvert replacements and extensions, realigning Boyce Road to create a new four‑way signalized intersection, and widening the I‑376 westbound off‑ramp at Exit 62.
Traffic impacts and schedule
Drivers will not be shocked to hear there are lane closures in their future. Motorists should expect periodic lane restrictions and flagger‑controlled delays between Keiners Lane and McMichael Road during the initial phase that begins March 9, with eastbound travel maintained and two‑way traffic preserved in key stretches, according to WPXI. Later phases will shut portions of the road to westbound traffic and send drivers onto signed detours, although officials say homes and businesses will remain reachable throughout construction.
Local reaction
Nearby business operators are bracing for a bumpy stretch before the payoff. Owners told the West Hills Gazette they expect major short‑term headaches, with one calling the start of construction “a nightmare.” Township leaders, however, are betting the disruption will be worth it, arguing the upgrades will ease long backups. Robinson Township officials note the corridor feeds multiple business parks and say intersection improvements should noticeably improve daily commutes once the dust settles.
Why it matters
Engineers estimate the corridor handles roughly 15,000 vehicles a day in design projections, and the rebuild is intended to increase capacity, modernize stormwater management and cut down on ponding that has repeatedly forced closures after heavy rain. Those design details and traffic projections are laid out on the project page from SAI Consulting Engineers.
How to follow updates
The Department of Public Works plans to roll out advance notice of each phase, including closures and detours, through press releases and social channels. Past county statements show the department leans on Allegheny Alerts and media releases to keep residents in the loop. For a sense of how those notices look, and for media contact information, see the Allegheny County Department of Public Works' news release on a previous Campbells Run Road reopening.
