About 1,500 miles of Michigan state highway will see a speed limit increase starting on May 1.

The Michigan Department of Transportation (MDOT) says 900 miles will see an increase to 65 mph, and 600 miles will see an increase to 75 mph.

Public Act 445, passed by the state Legislature in late 2016, tasked MDOT and Michigan State Police with increasing speed limits on some state highways and freeways based on 85th-percentile speeds (the speed at or below which 85 percent of traffic is moving) and the results of engineering and safety studies.

The law requires that these modified speed limits be in place prior to Jan. 5, 2018.

Work has already begun at the MDOT Statewide Sign Shop to update signs for the areas about to see an increase in the posted speed limit.
