Early Friday morning, a routine run through the Allegheny Tunnel on the Pennsylvania Turnpike turned into a smoky mess, as a vehicle fire choked the tube with haze and forced scores of motorists to abandon their cars along the mountain corridor.
New video from the scene showed the tunnel thick with smoke as emergency crews moved in and guided drivers to safety. In footage shared with Pittsburgh's Action News 4, the normally orderly traffic tube looked more like a fogged-out movie set while responders worked to get people out.
According to WTAE, PennDOT said roughly 150 people from nearly 80 vehicles evacuated the tunnel. Evacuees were taken by bus to a PennDOT maintenance shed, and emergency dispatchers said one person was flown to a Pittsburgh hospital. Officials said drivers were able to return to their vehicles around 2:45 a.m. after the scene was cleared.
"It really looked like a scene from Dante's Inferno — without the flames," evacuee Viviana Altieri told WTAE, describing the thick smoke and confusion inside the tunnel. She also praised emergency crews for their fast response and clear instructions as passengers were escorted from their cars.
Why the Allegheny Tunnel Is Under the Microscope
The Allegheny Mountain Tunnel is one of the longest and oldest active tunnels on the turnpike, and it has been at the center of a long-running realignment and modernization push aimed at improving safety and reducing closures. The Pennsylvania Turnpike Commission says the Allegheny Mountain Realignment Project would replace or bypass aging tunnels to limit disruptions, and incidents like overnight vehicle fires underscore why upgrades remain a priority. For commuters and truckers who depend on the corridor, even short shutdowns can trigger long detours and ripple-effect traffic delays.
