Montrose, South Dakota regulations require all heavy haul operations to comply with the South Dakota Department of Transportation (SDDOT) guidelines as well as local ordinances administered by the Montrose Department of Transportation (MONDOT).

Heavy haul permits are required for any load exceeding 11 feet in width, 15 feet 6 inches in height, or 171,154 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Montrose, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid Montrose Port Authority and the vicinity of the Montrose Marketplace, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

Escort vehicles are required for oversize loads exceeding 14 feet in width or 14 feet 0 inches in height on highways and certain city streets. The South Dakota State Police often require escorts for loads that are particularly large or heavy.

For movements within Montrose, the Montrose Department of Transportation may mandate police escorts for oversize loads, especially during peak traffic hours. Scheduling these escorts requires advance notice, typically at least 68 hours prior to the move.

Permit applications in Montrose must be submitted through the SDDOT's online permitting system. Carriers should be prepared to provide comprehensive vehicle specifications, proposed routes, and transport schedules.

Applications must include certified weight tickets, dimensional diagrams, and route surveys. For loads that may impact traffic flow in Montrose, a traffic management plan may also be required as part of the application process.

Montrose has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-8 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Montrose Holiday Fair and the the Montrose Fall Games, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Montrose and areas around Downtown Montrose, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.

The base permit fee for an oversize load in South Dakota is $40, with additional fees for super heavy loads (over 200,000 lbs) ranging from $150 to $350 depending on the complexity of the move.

For movements within Montrose, Montrose Department of Transportation may charge additional fees for city-specific permits, which can range from $75 to $500 or more for particularly complex routes or those requiring extensive coordination with city agencies.
