Legal in Parts of Michigan, But Nowhere Else Within 700 Miles
There's something that's legal in parts of Michigan that you can't legally do anywhere else for roughly 700 miles.
As a matter of fact, Michigan is one of only two states east of the Mississippi River where it's legal to do this in some places.
Michigan Speed Limits
Back in 2017, laws increasing the maximum speed limit to 75 miles per hour on some Michigan highways went into effect.
The change affected some 614 miles of Michigan roadway, including parts of Interstates 69 and 75, as well as portions of U.S. Highways 10, 31, 127 and 131.
Portions of Michigan highway where it's legal to travel 75 mph include:
- I-69 between East Lansing and Swartz Creek
- I-69 from the Genesee/Lapeer County line to Port Huron
- I-75 from Bay City to Mackinaw City
- I-75 from St. Ignace to Sault Ste. Marie
- U.S. 10 from Bay City to Clare
- U.S. 31 from Scottville to near Rothbury
- U.S. 127 from just north of Lansing to St. Johns
- U.S. 127 from Ithaca to just south of Grayling
- U.S. 131 from near Rockford to just north of Manton
Where Else in the US Can You Legal Travel 75mph or More?
According to the U.S. Department of Energy, Michigan is one of only two states east of the Mississippi River to have passed laws allowing motorists to travel 75 mph legally on some sections of highway - Maine being the other.
If you left Michigan, you'd have to travel all the way to Arkansas before you'd see a section of highway with a speed limit of 75 mph or higher again.
Maximum speed limits of 75 mph or higher are much more common in more rural areas of the United States west of the Mississippi River. Other states with maximum speed limits of 75 mph on portions of highway include Louisiana, Kansas, Nebraska, North Dakota, Colorado, New Mexico, Arizona and Washington.
Several states have areas where it's legal to travel 80 mph in some places: Oklahoma, South Dakota, Montana, Idaho, Wyoming, Utah, and Nevada.
It's legal to travel 85 mph in some parts of Texas!
