A fatal head-on crash on I-70 westbound in Washington County, Pennsylvania closed about five miles of the corridor for three hours today, Thursday, May 7, 2026, and the highway is still running on a single lane. Pennsylvania State Police say a Ford Focus crossed the grass median near mile marker 10.5 in Buffalo Township at 1:22 PM EDT and collided with a westbound tractor-trailer.
What Happened
- Time and location: 1:22 PM EDT, mile marker 10.5, Buffalo Township between Pittsburgh and the West Virginia state line
- Vehicles: Ford Focus eastbound, tractor-trailer westbound
- Mechanism: Median crossover into oncoming westbound traffic
- Outcome: Ford Focus driver pronounced dead on scene; tractor-trailer driver treated for minor injuries
- Closure: I-70 westbound between Exit 11 (Taylorstown) and Exit 6 (Claysville)
Detour and Corridor Status
PennDOT routed traffic onto Route 40, the parallel two-lane that traces the original National Road through Claysville and Taylorstown. The detour adds roughly 20 minutes off-peak and significantly more under truck load. This stretch of I-70 carries heavy Pittsburgh-to-Wheeling freight and runs without cable median barrier, which PennDOT District 12 has flagged in prior corridor safety reviews. Single-lane operation continues through the evening commute. Live status is on 511PA.
Median Crossovers and Driver Safety
Median-crossover crashes are among the deadliest on rural interstates, and head-on impacts at highway speed routinely exceed survivable forces even with modern airbags and crumple zones, particularly against a fully loaded semi. Lane-keep assist and lane-departure warning cut median departures by roughly half in IIHS testing, and body-on-frame trucks and SUVs measurably outperform unibody sedans in cross-over impacts.
Timing
Westbound I-70 reopened to a single lane at 4:25 PM EDT and the corridor is expected to stay restricted through the evening as state police complete reconstruction and the coroner’s office concludes scene work. We’ll update this article as conditions evolve.
