FRAZER, Pa. (CBS) — A tractor-trailer crash shut down a heavily-traveled road in Chester County Tuesday morning for nearly three hours.

The accident happened shortly after 5:30 a.m. in the northbound lanes of Route 202 between Route 30 and Route 401. The crash happened right before the Frazer exit.

The crash remains under investigation.
