ANN ARBOR, MI – With about six months of construction left on the U.S. 23 Flex Route project, there’s still a lot of work to do.

The Michigan Department of Transportation is adding a rush hour lane on the inside shoulder of both directions of U.S. 23 from Ann Arbor to M-36 in Livingston County to relieve traffic congestion.

Construction started in the fall of 2016 and ramped up this spring.

Here’s a look at what’s going on now and what’s to come:

Between Eight Mile Road and M-36, crews are placing banks and sand sub-bases along the outside shoulder of southbound U.S. 23.

Between Barker Road and Eight Mile Road, two lanes of northbound and two lanes of southbound traffic are on the northbound roadway as crews reconstruct the existing southbound lanes and the Great Lakes Central Railroad bridge and repair the Barker Road bridge.

When that’s done in mid- to late August, MDOT will shift traffic to the southbound lanes to work on the northbound side.

Dan’s Excavating crews are pouring the new bridge deck on North Territorial Road. The interchange at U.S. 23 and North Territorial should reopen by June 15.
