MDOT determines when weight restrictions begin each spring by measuring frost depths along federal highways, observing road conditions and monitoring weather forecasts. The weight restrictions remain in place until the frost line is low enough to allow moisture to escape and the platforms become stable again. When frost melts under a paved road, the platform becomes wet and spongy as water is trapped between the pavement and the remaining ice layer below. If trucks and heavy equipment roll on a layer of concrete or asphalt that is not well supported underneath, many permanent cracks can occur. Several Mid-Michigan County street commissions issued weight restrictions during what is known as an unusual thaw in January. One of the most common business interactions with a county road authority involves seasonal weight restrictions — sometimes referred to as “freeze laws.” Although roads are made of concrete and asphalt and seem indestructible, they can be very fragile at the end of winter when frost comes out of the ground. Even heavy late winter sunshine on the dark paved surface has a significant impact on a road.

Most often, also consult nearby road agencies. By law, road authorities can impose weight restrictions on all roads that are not designed as “year-round” roads. The roads throughout the season are much thicker and designed to be able to drive trucks all year round. Seasonal weight restrictions lower axle load limits and reduce maximum driving speeds for some vehicles.

Please note that some restricted categories are exempt from these restrictions after approval has been submitted. For MDOT featherweight restriction bulletins on the trunkline system, click here.

Due to the unusually warm temperatures, frost begins to thaw under roads in Bay, Midland and Saginaw counties and beyond, causing potholes to form and road authorities to impose weight restrictions, sometimes referred to as freezing laws. In Bay County, the restrictions will take effect Friday, Jan. 20 at 4 p.m. Weight restrictions have also been enacted in Saginaw, Midland, Isabella and Arenac counties, Lillo said.

Single axle: 18,000 lbs Tandem axle: 16,000 lbs/each axle Lillo, who has more than 13 years of experience in the Road Commission, has never experienced such an early thaw.

Torregrossa said evidence of the thaw can be found in Michigan`s agricultural fields. The maximum permissible gross axle load on year-round routes is:. Starting Monday, April 25, 2022, at 6 a.m., weight restrictions will be lifted on all highways in the state, from Michigan`s southern border north to the Mackinac Bridge, including the Mackinac Bridge. Freeze restrictions are still in place for the rest of the state and are imposed and enforced on all state highways north of the Mackinac Bridge.
