Drivers on the 62nd Street Bridge in Sharpsburg ran into serious trouble late Monday night when a semi-truck rolled over, and its trailer began leaking what responders described as a corrosive liquid. Allegheny County hazmat crews were called in, Route 8 northbound was shut down, and the span quickly turned into a full-scale emergency scene. No injuries were immediately reported, and crews stayed on site while tow work and cleanup plans were put in motion.
According to WPXI, the rollover happened on the Sharpsburg side of the Fleming (62nd Street) Bridge on July 6, and sources told the station the trailer was leaking a corrosive material. The Pennsylvania Department of Environmental Protection was notified, and Allegheny County HazMat responded. The local volunteer department, Southern Allegheny Valley Emergency Services, told the station that crews were preparing to enter the trailer to assess cleanup needs. PennDOT handled traffic control around the closure and estimated the bridge would remain shut into the night.
Bridge, inspections and detours
The 62nd Street span carries Route 8 between Sharpsburg and Pittsburgh and is maintained by the Pennsylvania Department of Transportation. PennDOT has posted inspection activity for the bridge this spring. With the closure in place, motorists were pushed onto detours while crews worked, adding time to trips for commuters heading to the North Side and nearby neighborhoods. For background on the bridge and recent inspection activity, see PennDOT.
Eyewitness accounts and traffic
Local residents shared photos and video of hazmat units and tow trucks blocking the span, and a Reddit thread quickly collected multiple on-the-ground reports and images from the scene. Commenters described a heavy emergency presence and vehicles being redirected off the bridge, and one onlooker linked directly to local TV coverage. Drivers were urged to steer clear of the area while crews set up a perimeter and evaluated environmental risks.
Cleanup and what to watch
Officials said crews would first identify the cargo and the material involved, then put containment and cleanup plans in place before the bridge could fully reopen. Environmental monitoring and sampling are standard in situations like this, and agencies typically coordinate water and air checks if contamination is possible. This story will be updated as agencies release more information and reopening times are confirmed.
