Late this evening Rescues 91 & 91-5 were alerted to a crash with a vehicle overturned.  Rescue, Engine and Lt 91 were responding when DCC advised that the crash was now in Harrisburg City and EMS was on scene with entrapment.  Due to already being close to the scene Company 91 continued and arrived to find 1 vehicle on the shoulder and another on its side on the wrong side of the barrier.  Crews quickly stabilized the vehicle and deployed a protection line while the Rescue Officer formed a plan with EMS.   Crews cut the windshield and removed the occupant to the care of EMS.  Harrisburg City units arrived during the extrication and supported the operations as well and providing care to other patients.
