Southbound lanes of Route 28 reopened early Wednesday morning after emergency crews worked overnight to clear the scene and repair damage following a tractor-trailer rollover accident.

The highway was shut down for nearly 10 hours after a diesel tanker truck crashed into a barrier and overturned, spilling fuel. The road was reopened around 3 a.m.

Allegheny County Emergency Services Chief Matt Brown praised the coordinated response to the incident, emphasizing the importance of local emergency efforts. “Every emergency disaster starts locally and ends locally,” Brown said. “This was a great mutual aid effort with the best possible outcome given the circumstances.”

To contain the fuel spill, the Pennsylvania Department of Environmental Protection (DEP) deployed a boom at the mouth of Pine Creek to prevent contamination of the Allegheny River.

“Our priority is protecting aquatic life and recovering as much diesel as possible,” Brown stated. However, it remains unclear how much fuel may have entered the creek.

Officials have alerted downstream drinking water facilities that could be affected. DEP crews are expected to continue environmental monitoring in the area throughout Wednesday.
