CONEWAGO, Pa. (AP/KDKA) — A state Department of Corrections bus that was carrying 38 inmates was involved in a crash on the Pennsylvania Turnpike early Friday, leaving a guard and 11 inmates with minor injuries.

The crash in the turnpike’s eastbound lanes in Conewago Township was reported shortly after 9 a.m. A stretch of the roadway was closed for a few hours as the accident was investigated.

A Corrections Department spokeswoman said all 38 inmates aboard the bus had been accounted for.

State police say they were called to the crash at mile marker 258.6 just before 9:30 a.m. Friday morning. They say the injured guard and inmates were being treated at a hospital for undisclosed injuries, while the 27 other inmates were also being evaluated there as a precaution.

Further details on the injuries were not disclosed, though none were considered life-threatening.

It wasn’t immediately known where the bus was headed to or if any other vehicles were involved in the crash.

The accident remains under investigation.
