A crash on an Interstate 94 exit ramp could slow traffic on the south side of Ann Arbor this morning.

The crash, believed to involve three vehicles, is on the exit ramp from westbound 94 to State Street, but is not blocking the ramp, a dispatcher with the Washtenaw County sheriff’s department said.

State police were on their way to the crash at 7:55 a.m., the dispatcher said.

Traffic slowdowns are shown in yellow and red on the map.
