Spring load limits for trucks are rolling into effect in multiple Midwest states, including Michigan and Wisconsin. Meanwhile, Minnesota and North Dakota are transitioning away from their winter-specific limits.
Updates in Michigan
Michigan’s Department of Transportation (MDOT) began enforcing spring weight restrictions on all state trunkline highways starting Monday, March 3. These measures aim to protect roadways as seasonal changes make them more vulnerable to damage.
MDOT provided the following guidelines for restricted areas:
- All-Season Routes: Legal axle weights remain unchanged on these routes.
- Oversize Loads: Extended permits remain valid in restricted areas. However, single-trip permits for loads exceeding 14 feet in width, 11 axles, 150 feet in total length, or for overweight loads will not be issued on restricted routes.
- Seasonal Routes: Weight reductions are set to 25% for rigid pavements and 35% for flexible pavements, with maximum speeds capped at 35 mph for select vehicles.
Additional details, including speed restrictions and rules for propane deliveries and service vehicles, are available on the Michigan Department of Transportation website.
Wisconsin Implements Class II Restrictions
On Thursday, March 6, Wisconsin’s Department of Transportation (WisDOT) enacted Class II weight restrictions for most of its state highways. More highways have started these restrictions Monday, March 10.
WisDOT emphasized that Class II roads are particularly prone to damage during spring, as thawing frost weakens the ground. Local governments within Wisconsin may also impose additional load limits or restrictions on county, town, city, and village roads.
To assist truckers and businesses, an interactive map detailing seasonal weight restrictions throughout the state has been made available online.
Other States’ Updates
Minnesota ended its winter truck load limits as of February 28, signaling the transition to spring requirements. Meanwhile, North Dakota implemented its spring load limits on Friday, March 7.
