Drivers can now go 65 miles per hour on M-231 in Ottawa County after the speed limit increased on Monday, July 10, 2017. The highway opened in 2015 with a 55 miles per hour speed limit.
Nearly two months ago, it was announced the speed limit would go up on the highway but MDOT has not put up the new signs yet. MDOT first focused on getting 70 mph signs changed to 75 mph on 600 miles of freeways, mostly in northern lower Michigan.
Internal emails obtained by the 13 Watchdog team last year showed leaders at the Michigan State Police believed the speed limit was under posted and should be raised. There was a wide belief last year the majority of people felt comfortable driving faster and the road was designed to handle higher speeds.
