All oversize loads entering the City of Pinesdale, Ravalli County, must conform to the requirements set by the Montana Department of Transportation (MDT). This includes adherence to state-wide regulations regarding vehicle dimensions, weight limits, and safety equipment.

In general, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, or exceeding 80,000 lbs gross vehicle weight should obtain an oversize load permit from the MDT. The Pinesdale Public Works Department may have additional requirements for local routes.

Due to the presence of historic structures and narrow roadways within Pinesdale's downtown area, loads exceeding 10 feet in width may require a pre-approved route survey. Contact the Pinesdale Public Works Department at least one week prior to your planned transport for guidance.

Escort vehicles are required in Pinesdale when the load exceeds 12 feet in width, 14 feet 6 inches in height, or 100 feet in length. Front and rear escorts may be necessary depending on the specific route and potential traffic congestion.

Local police escorts through Pinesdale are typically only required for extremely large or complex loads that pose a significant risk to public safety. If a police escort is deemed necessary by the MDT or Pinesdale Public Works, you'll need to contact the Ravalli County Sheriff's Office to schedule the escort and confirm associated fees. Expect a minimum of 48 hours' notice for scheduling.

To apply for oversize load permits affecting routes within Pinesdale, you'll generally need to start with the Montana Department of Transportation's online permitting system. The MDT website (www.mdt.mt.gov) provides access to the permitting portal and detailed instructions.

In addition to the standard MDT application requirements, be prepared to provide detailed route information, including specific street names and any planned deviations from designated truck routes within Pinesdale. The Pinesdale Public Works Department may request additional documentation, such as detailed load diagrams, for loads requiring special routing considerations.

Time-of-day restrictions may be in effect for oversize loads traveling through Pinesdale during peak traffic hours, generally between 7:00 AM and 9:00 AM and between 4:00 PM and 6:00 PM on weekdays. Check with the Pinesdale Public Works Department for specific restrictions applicable to your route.

Seasonal weight restrictions may be imposed on certain roads within Pinesdale during the spring thaw (typically March-May) to prevent damage to road surfaces. These restrictions are typically announced by the MDT and the Ravalli County Road Department.

Commercial vehicles exceeding 10 tons are prohibited from using Main Street between 1st Avenue and 5th Avenue in Pinesdale due to load-bearing limitations of the historic roadbed. An alternate route along Highway 93 is required for these vehicles.

Permit fees for oversize loads in Montana are determined by the MDT based on factors such as distance traveled, load dimensions, and weight. Fees are generally calculated per mile and vary depending on the specific circumstances.

While the base permit fee is set by the MDT, additional fees may be assessed by the Pinesdale Public Works Department for route surveys, traffic control, or other services required to facilitate the safe transport of oversize loads through the city.
