Two crashes are slowing traffic on northbound US-23 on the east side of Ann Arbor this afternoon.

One is just north of Geddes Road, and the other is north of I-94, a dispatcher with the Washtenaw County Sheriff’s department said.

Michigan State Police had been on the scene of the crash north of Geddes Road about 20 minutes, the dispatcher said at 2:45 p.m. and had not arrived at the second one, he said.

No further information, including whether lanes are blocked or whether there are any injuries, was immediately available.
