Arlington, 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 Arlington Department of Transportation (ARLDOT).

Heavy haul permits are required for any load exceeding 12 feet in width, 14 feet 6 inches in height, or 176,456 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Arlington, particularly in high-traffic areas.

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

South Dakota law mandates escort vehicles for any load exceeding 16 feet in width or 15 feet 0 inches in height. When traveling through Arlington, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Arlington Department of Transportation requires a minimum of 50 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Arlington.

The South Dakota Department of Transportation manages the primary application process for oversize permits, with supplementary permits required from Arlington Department of Transportation for transit through Arlington limits.

Required documentation for Arlington permits includes axle configuration diagrams, proof of insurance with appropriate coverage levels, and detailed transport plans. Engineering assessments may be required for loads exceeding standard weight thresholds on certain streets and bridges.

Arlington has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-9 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Arlington Cultural Exposition and the the Arlington Music Festival, which may impact routing and scheduling.

Certain neighborhoods, such as Arlington Center and areas around Arlington Medical Center, 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 Arlington, Arlington 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.
