One lane of eastbound Interstate 94 on the southeast side of Ann Arbor will be closed overnight three days this week for work by the Michigan Department of Transportation.

The right lane and the right shoulder of the road will be closed from 9 p.m. to 5 a.m. Wednesday through Friday this week, according to MDOT.

Workers will be removing and replacing the cantilevered sign just east of the Carpenter Road overpass east of the U.S. 23 interchange near mile marker 180, said Mark Sweeney, manager of MDOT's Brighton Transportation Service Center.

Drivers on I-94 will be warned of the closure before reaching U.S. 23 with a notification sign.

A traffic backup on I-94 outside of MDOT's construction zone in November contributed to a fatal accident that killed a 43-year-old Ann Arbor man.

Drivers had slowed on the freeway to merge into one lane between U.S. 23 and South State Street to accommodate a MDOT sign replacement crew that was working about 7 a.m. on a Saturday.

Sweeney said MDOT will be conducting work only within the 9 p.m. to 5 a.m. time frame to avoid affecting traffic at peak times.

MDOT has been replacing signs along its freeways for the past year with new signs that have bigger fonts and are more reflective so they can be seen better at night.

Sweeney said MDOT expects to have all signs in Washtenaw County on its freeways replaced by the end of April.

Also this spring, MDOT will begin replacing signs on non-freeway routes it owns and operates in Washtenaw County, Sweeney said.
