In a continuation of the Michigan Department of Transportation's sign upgrade project, two lanes of eastbound Interstate 94 will be closed near the Zeeb Road exit overnight Friday and Saturday in Scio Township.

From 10 p.m. Friday to 5 a.m. Saturday, and from 10 p.m. Saturday to 5 a.m. Sunday, two lanes of eastbound I-94 will be closed near the Zeeb Road exit.

That portion of I-94 is three lanes wide in each direction.

Throughout the past year, MDOT has been replacing signs along its freeways with new, more reflective signs with bigger fonts so they're more visible at night.

Lane closures around the Ann Arbor area on I-94 have been in place throughout recent weeks — the most recent of which was late Thursday night to Friday morning at M-52 near Chelsea.

MDOT expects to complete its sign replacement project on freeways in Washtenaw County by the end of April. The agency will then move to replace signs on non-freeway routes it owns in the county.
