1) Go the the MnDOT website to get your annual permit for federal highways and state trunk highways.

2) Check with cities, counties and townships (local road authorities) to find out if you need any additional permits for what they choose to identify as "preferred routes."

Background on the new truck weights law

The 2017 Minnesota Legislature passed the Road Construction Materials Special Permit authorizing road authorities in Minnesota to issue overweight permits for trucks carrying road construction materials and complying with MN Stat. 169.824.
 
The legislation authorizes state and local road authorities to issue permits for vehicles with six or more axles to haul road construction materials and be operated with a gross vehicle weight of up to 90,000 lbs.; and seven or more axles to haul road construction materials and be operated with a gross vehicle weight of up to 97,000 lbs. Permitted vehicles are also eligible for Ten Percent Winter Weight Increase (Seasonal). Permit revenues are dedicated to the local bridge inspection and signing account.
 
The Road Construction Materials Special Permit became effective on January 1, 2018.
 
Annual permits for the entire federal (non-interstate) and state trunk highway systems are issued by MnDOT through the MnDOT Office of Commercial Vehicle Operations. Local road authorities are responsible for issuing permits on their systems. Road construction materials industry companies should contact the local road authority where they intend to use these vehicles to discuss the local preferred routes or authorization process in that county.

The legislation encourages local road authorities to identify local preferred routes and may adapt maps created for spring load restrictions to identify 10-ton and 9-ton roads as the basis for the local preferred routes. The map could also identify posted bridges on those routes as well construction materials plants served by the system including aggregate mining facilities, ready mix concrete plants, permanent and portable hot mix asphalt plants, cementitious and oil terminals, and recycled road materials facilities. Permit holders would be limited to these routes when carrying overweight loads.

This legislation was based on the experience of 65 counties who have annually authorized more than 1,500 six and seven axle vehicles carrying raw or unprocessed agricultural products since 2008 (MN Stat.169.865).

Permit holders anticipate using these vehicles to more efficiently move construction materials:

  • On defined routes between permanent facilities including aggregate shipments from the pit/quarry to a ready mix concrete or asphalt plant, cement shipments to ready mix concrete plants, aggregate transfers between pits/quarries, etc.
  • On defined routes between temporary facilities including aggregate shipments to a portable asphalt or concrete plant, etc.
  • On haul roads to road construction projects from aggregate facility, asphalt plant, concrete plant, etc.
