Seasonal Weight Restrictions
On Thursday, April 9, 2020, the Portage County Highway Department will be removing seasonal weight restrictions on all County Trunk Highways East and South of the Wisconsin River with the exception of CTH X and CTH DB. All County Trunk Highways West of the Wisconsin River along with CTH X and CTH DB will remain posted until conditions change. Once a final date has been determined, a separate press release will be sent out for the remaining roads.
Additional information can be obtained by contacting the Highway Department office at (715) 345-5355 or on our website at http://www.co.portage.wi.us/department/highway-department/highway-weight-restrictions.
Please note that these weight restrictions are for County Trunk Highways only. Any weight restrictions on State, City, Village, or Town roads are handled by each individual municipal entity.
Every Spring, the Portage County Highway Department posts weight restrictions on a majority of our roadway system in order to preserve the life of our roadways during its most vulnerable time during Spring thaw. The roads are posted with a 6 ton maximum single axle load and 10 ton maximum tandem axle load. Attached to this letter is the Wisconsin Transportation Bulletin: Using Weight Limits to Protect Local Roads. This bulletin provides a comprehensive summary of the need for protecting local roads as well as information on the authority of local governments to exercise this control.
Beginning in 2015, the Portage County Highway Committee has held discussions regarding the County’s past practice in approving seasonal-overweight permits during the Spring posting season. Past practice of the department has been that the Commissioner has reviewed any requests for “perishable” goods and emergency requests and the Highway Committee has reviewed requests for wood products. These discussions have led to the creation of the attached policy which was approved by the Highway Committee at their February 14, 2017 meeting and later amended at their February 28, 2017 and February 6, 2018 meetings.
In order to be considered for a variance permit, applicants must meet the requirements of the policy and must fill out the attached Request Form. The Request Form may be written or filled out electronically.
When completed, please submit the Request Form through any one of the following methods:
Mail: 800 Plover Road, Plover, WI 54467
Please note that Request Form must be filled out in its entirety to be considered.
Oversize/overweight (OSOW) vehicles traveling on Portage County Highways must obtain permit coverage. Permit applications may be obtained by contacting the Highway Department office at (715) 345-5355.
OSOW vehicles traveling on municipal roads and streets must obtain permit coverage from the municipality. OSOW vehicles traveling on state highways must obtain permit coverage from the Wisconsin Department of Transportation (WisDOT).
