Des Arc, Missouri regulations require all heavy haul operations to comply with the Missouri Department of Transportation (MODOT) guidelines as well as local ordinances administered by the Des Arc Department of Transportation (DESDOT).

Heavy haul permits are required for any load exceeding 12 feet in width, 15 feet 0 inches in height, or 190,688 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Des Arc, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid the Des Arc Canal and the vicinity of the Des Arc River, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

Missouri law mandates escort vehicles for any load exceeding 15 feet in width or 14 feet 6 inches in height. When traveling through Des Arc, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Des Arc Department of Transportation requires a minimum of 52 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Des Arc.

Permit applications in Des Arc must be submitted through the MODOT's online permitting system. Carriers should be prepared to provide comprehensive vehicle specifications, proposed routes, and transport schedules.

Applications must include certified weight tickets, dimensional diagrams, and route surveys. For loads that may impact traffic flow in Des Arc, a traffic management plan may also be required as part of the application process.

Des Arc has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-8 am and 4-6 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Des Arc Holiday Exposition and the the Des Arc Historical Marathon, which may impact routing and scheduling.

Certain neighborhoods, such as Des Arc Center and areas around Des Arc Civic 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 Missouri 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 Des Arc, Des Arc 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.
