Heavy haul permits are required for any load exceeding 11 feet in width, 13 feet 0 inches in height, or 206,383 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Cavour, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid Cavour Historic District and the vicinity of Cavour International Airport, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

In Cavour, South Dakota, loads wider than 15 feet or taller than 14 feet 0 inches must be accompanied by certified escort vehicles. Additional escorts may be required based on the specific route and time of travel through urban centers.

Cavour regulations state that police escorts must be arranged at least 48 hours before transport for loads that will impact major thoroughfares or require temporary traffic control measures.

To apply for an oversize load permit in South Dakota, companies must submit their applications through the South Dakota Department of Transportation's permit portal. Additional permits for Cavour may require submission to Cavour Department of Transportation.

Documentation required includes detailed route plans, load dimensions, and weight certificates. For super heavy loads, a detailed engineering analysis may be necessary to ensure that the load can be safely transported without damaging city infrastructure.

Cavour has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Cavour Holiday Show and the the Cavour Music Fair, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Cavour and areas around the Cavour Bay, 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 Cavour, Cavour 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.
