It happened at 2:00 a.m. Tuesday in the northbound lanes near Exit 8 for Blackwood-Clementon Road.
Two people were hurt in the crash, one of them seriously.

Things got worse just after 5 a.m. when a truck overturned on that exit ramp from Rt. 42 Northbound to College Drive, where traffic was being diverted.
