Four-car crash reported on U.S. 23 ramp to Washtenaw Avenue

The crash, on the ramp from northbound U.S. 23 to westbound Washtenaw Avenue, was not believed to be blocking traffic, but a Google traffic map showed a significant backup in the northbound lanes of the freeway.

It was not clear whether injuries were involved, a dispatcher with the Washtenaw County Sheriff's Office said.

Michigan State Police were on the way to the crash at 7:45 a.m., the dispatcher said.
