Multi-Vehicle Crash Closes I-79 North

A multi-vehicle crash Tuesday morning closed the northbound lanes of Interstate 79 in North Strabane Township.  Washington County 9-1-1 says it happened just after 7 a.m just past the Canonsburg exit.  Two people were transported by ambulance from the scene but dispatchers describe their injuries as non-life threatening.  According to dispatchers, a pest-control truck was involved in the crash and overturned spilling chemicals.  That led to a Haz-Mat response.   State Police Washington say both lanes northbound were closed until just after 9:30 am.
