All oversize loads entering Tolna, North Dakota must conform to the requirements set by the North Dakota Department of Transportation (NDDOT) and the Tolna Department of Transportation (TOLDOT).

In general, any vehicle over 13 feet in width, 16 feet 6 inches in height, and within the super heavy weight class (over 222,353 lbs) should obtain an oversize load permit from the NDDOT and potentially additional permits from TOLDOT.

To navigate the complexities of Tolna's infrastructure, it's crucial to plan routes that avoid sensitive areas like the Tolna Marketplace and major construction zones along the Tolna Industrial Park area.

North Dakota law mandates escort vehicles for any load exceeding 14 feet in width or 13 feet 6 inches in height. When traveling through Tolna, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Tolna Department of Transportation requires a minimum of 24 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Tolna.

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

Required documentation for Tolna 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.

Tolna has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-9 am and 4-6 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Tolna Heritage Convention and the the Tolna Spring Parade, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Tolna and areas around Tolna College Campus, 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 North 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 Tolna, Tolna 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.
