Speed limits will be going up on a number of Michigan freeways and highways.

The Michigan State Police and MDOT say speed limits along 600 freeway miles in Michigan can be safely increased to 75 miles per hour and 900 miles of highways can go up to 65 miles per hour.

This includes US-131 from M57 in Kent County through Montcalm, Mecosta, Osceola, and Wexford counties to where the freeway ends north of Manton and US-10 from M-115 to I-75 through Clare, Isabella, Midland, and Bay counties.

MDOT says they will begin posting the new speed limits starting May 1.
