How long does it take to get a Single Trip permit?

  1. The Permit Office has a 2-hour turn around time for the issuance of Single Trip permits.  We will not guarantee that applications received after 3:00 p.m. (MT) will be processed on the same business day.  Applications are processed in the order in which they are received.

  2. The turn around time for the issuance of Chapter 6 Specials (Superloads) is 3-5 business days.  (NOTE: due a shortage of staff in the Bridge section and an increase in applications, it may take 2-3 weeks to process a Chapter 6 Special permit.  Please submit applications and supporting documents well in advance so the application can placed into the queue for processing.)

Our busiest days of the week are typically Mondays and Fridays.  We recommend that applications be submitted early in the day to avoid delays.
