Oversize & Overweight Vehicle Permits

Oversize-Overweight vehicles are requested to stay on State Routes as much as possible. Will County Highway Staff will suggest alternate routes when applicable.
      
The Will County Division of Highways follows the IDOT fee schedule (except for containerized grain and bulk permits).
                 
Roads on the Will County Highway System are classified as "Local Roads and Streets" except for those with a posted weight limit, a posted height limit, and those designated Class II. Bridges over Interstate Highways are the jurisdiction of the State of Illinois. Overweight movements across these bridges require an IDOT Permit Number.
   
The following are the height and weight limitations on Local Roads and Streets. Any vehicle exceeding these amounts requires a permit from the Will County Division of Transportation. Permits may be issued for an overheight and overweight load providing it consists of one object that cannot be reasonably dismantled or disassembled.
