Because of the unusually warm winter, the Washtenaw County Road Commission last week suspended seasonal weight restrictions until further notice.

Seasonal weight restrictions are mandated to help minimize the impact of heavy trucks on Michigan's roads during the spring cycle of freezing and thawing, according to the County Road Association of Michigan.

“By law, road agencies can enact weight restrictions on roads that are not designated as all-season routes when conditions merit,” CRAM information states.

Normally, these restrictions take effect on March 1.

Seasonal restrictions lower the axle-loading limits and reduces the maximum travel speed for certain vehicles. For more details about seasonal weight restrictions, click here.

There are some exceptions, however, and those can be found here.
