Mulberry, Oklahoma regulations require all heavy haul operations to comply with the Oklahoma Department of Transportation (OKDOT) guidelines as well as local ordinances administered by the Mulberry Department of Transportation (MULDOT).

Heavy haul permits are required for any load exceeding 13 feet in width, 16 feet 0 inches in height, or 253,640 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Mulberry, particularly in high-traffic areas.

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

Oklahoma law mandates escort vehicles for any load exceeding 17 feet in width or 13 feet 0 inches in height. When traveling through Mulberry, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Mulberry 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 Mulberry.

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

Required documentation for Mulberry 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.

Mulberry 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 Mulberry Holiday Exposition and the the Mulberry Food Celebration, which may impact routing and scheduling.

Certain neighborhoods, such as Mulberry Center and areas around Mulberry Arena, 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 Oklahoma 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 Mulberry, Mulberry 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.
