Section of northbound I-95 collapses in Philadelphia after tanker truck catches fire underneath highway

A section of northbound I-95 in Philadelphia has collapsed after a tanker truck caught fire underneath the highway, Philadelphia officials said Sunday morning.

At least one vehicle is still trapped under the collapsed highway, Pennsylvania Gov. Josh Shapiro said at a Sunday afternoon news conference.

The governor said authorities are working to identify any individual or individuals caught in the fire and the collapse, which occurred around 6:20 a.m.

A commercial truck carrying a petroleum-based product is thought to have caused the fire, based on preliminary reports, Shapiro said.

"All hands are on deck to repair this as safely and as efficiently as possible," the governor said.

The fire is now under control, according to Philadelphia Mayor Jim Kenney. "We are advising residents to please avoid the area and plan for alternative routes of travel," he said at the news conference.

"In addition to road closures, we expect delays of trash collection and SEPTA bus routes in the area," he said.
