Improved Map Resources from the MnDOT Oversize/Overweight Permits Section

We now have two new mapping resources made available to help guide you in planning and scoping of Oversize/Overweight load movement:

  • SUPERLOAD Utility Resource Map
    This mapping tool can help you filter clearances on MnDOT utility lines, overhead signs, and light signals on state highways, and details on electrical services in different areas of Minnesota.

  • Width of Roadway Map
    This mapping tool displays travel lane widths for MnDOT’s two-lane undivided highways in three different travel lane width classes: 10 ft., 11 ft., 12ft. or greater. You can also view the location of Metro rush hour zones and restricted travel areas.

Please note that due to various external factors, such as new construction and physical changes in highways, this information may not be current, and may be incomplete. See our disclaimer for more information.

MnDOT makes change to annual permit trip logging requirement permanent

Trips made under a MnDOT annual permit no longer require a route pre-approval through MnDOT's permitting system whenever the loaded vehicle does not exceed the following dimensions:

  • 11'0" Wide;
  • 14'6" High; or
  • 110'0" Long.

MnDOT strongly encourages using its permit routing system to verify all routes, but it is no longer a requirement when loaded dimensions are within those listed above.
Loads exceeding the dimensions listed above, and overweight loads, are still required to obtain route pre-approval from MnDOT.
For complete details about this permanent requirement change, see memo.
