Overturned Big Rig on Auto Mall at 880

A big rig has overturned on the 880 off ramp to Auto Mall just before 2 o'clock this afternoon.  If this is the southbound off ramp then the afternoon commute may not be impacted.  The driver is out of the vehicle with unknown injuries.  The Peterbilt tractor is pulling a loaded trailer of unknown contents.  Great America is en route with a heavy duty tow.  CHP is reporting this on the northbound off ramp and it appears the big rig was making a left hand turn onto Auto Mall and rolled over onto the right hand shoulder of westbound Auto Mall.
