ADRIAN — Road work ahead.

Although official construction doesn’t begin for another week, signs are up for the roundabout project in downtown Adrian.

The preparation work started this past week, with workers relocating utilities, Kari Arend, spokeswoman for Michigan Department of Transportation, said Monday.

The one-lane roundabout will be put in at the intersection of M-52, Broad, Church and State streets. The project is being led by MDOT. The only involvement on the city of Adrian’s part was its request to have a roundabout put there to improve traffic flow and purchase a property along the route for it.

The roundabout will have four pedestrian crossing areas, with traffic islands to allow people crossing to wait while traffic flows. There also will be lights in the road marking the roundabout and a center island built to take an inadvertent tire drive-over by a larger truck. Frosty Boy will have two access points — one off of Church Street and one on Broad Street.

When work begins, southbound traffic will be detoured while northbound traffic will shift to accommodate part-width construction.
