An apparent hazardous materials incident has closed both lanes of eastbound Huron Street in downtown Ann Arbor.

The road is closed between Main and Fifth Avenue. The area is cordoned off near Main and Huron and Main and Fourth. It appears the issue is confined to an alley off Huron Street to William Street. The road also is blocked off at that side.

The HAZMAT truck arrived at the scene at about 12:20 p.m. No further details were available.
