There was a bizarre collision on Interstate Five at Lake Shasta Wednesday. At 9:48AM a Fed Ex delivery box van rear-ended a big rig on Northbound I-5 just north of Bailey Cove near the O’Brien Rest Area. The crash blocked one lane of the freeway. Both drivers sustained minor injuries. There was some difficulty in clearing the wreckage because the Fed Ex van had become impaled onto the back of the tractor-trailer.
