Truck Permits

The City of Grand Junction requires all Oversize/Overweight Trucks that are traveling on City Streets to contact the City for a Letter of Authorization (LOA). Why Truck Routes? Grand Junction/Mesa County is the regional economic center for Western Colorado and Eastern Utah. Trucks are the primary delivery systems for the vast majority of consumer goods brought into our community. To address these concerns, a comprehensive plan was developed to identify a network of truck routes to support safe and efficient truck operations while satisfying the public need for adequate protection and separation.

LOA

The following City of Grand Junction LOA's are available:

  • Single Trip LOA: An LOA that is valid for a single move, on a designated route(s) for Extra-legal Vehicle or Loads.
  • Multi Day LOA: An LOA that is valid for a specific time period on the designated route(s) for Extra-legal Vehicle or Loads.
  • Annual LOA: An LOA that is valid for one year from the date of issuance on the designated route(s) for Extra-legal Vehicle or Loads.

If any of the routes being used are within Mesa County or State of Colorado Department of Transportation's jurisdiction, a permit must be acquired from those entities. A draft LOA will be issued to be provided to those entities. After acquiring the required permits and providing the permit numbers to the City, a final LOA will be issued.
