All oversize loads entering Reliance, South Dakota must conform to the requirements set by the South Dakota Department of Transportation (SDDOT) and the Reliance Department of Transportation (RELDOT).

In general, any vehicle over 12 feet in width, 15 feet 0 inches in height, and within the super heavy weight class (over 298,423 lbs) should obtain an oversize load permit from the SDDOT and potentially additional permits from RELDOT.

To navigate the complexities of Reliance's infrastructure, it's crucial to plan routes that avoid sensitive areas like Reliance Shopping District and major construction zones along the Reliance Convention Center area.

South Dakota law mandates escort vehicles for any load exceeding 14 feet in width or 13 feet 0 inches in height. When traveling through Reliance, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Reliance Department of Transportation requires a minimum of 35 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Reliance.

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

Required documentation for Reliance 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.

Reliance has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-8 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Reliance Music Parade and the the Reliance Arts Parade, which may impact routing and scheduling.

Certain neighborhoods, such as Reliance Center and areas around Reliance Historic District, 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 Reliance, Reliance 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.
