Oversize-Overweight Permits

Urgent: Permits suspended in Ashland, Bayfield, Douglas and Iron counties.

All Oversize-Overweight (OSOW) permits (single and multiple) are suspended in Ashland, Bayfield Douglas and Iron counties until further notice due to flooding and system damages related to the recent storms. All carriers and drivers should check 511 before any transit as the affected list of counties may increase as weather conditions continue and further system evaluations are convened. Legal loads should also check 511 for structural restrictions and alternate route information. 511 will continue to be updated as conditions change.

Permit suspension does not apply to equipment and materials needed for system restoration efforts! Carriers need to identify that when submitting applications.

Please note: Counter hours and procedures have changed for the Oversize/Overweight Permit Unit. Learn more about these changes.

WisDOT recommends that carriers and drivers routinely monitor the WisDOT website and 511 Wisconsin for roadway closure or restriction information.
