Zinc, Arkansas regulations require all heavy haul operations to comply with the Arkansas Department of Transportation (ARDOT) guidelines as well as local ordinances administered by the Zinc Department of Transportation (ZINDOT).

Heavy haul permits are required for any load exceeding 13 feet in width, 14 feet 6 inches in height, or 287,640 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Zinc, particularly in high-traffic areas.

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

Escort vehicles are required for oversize loads exceeding 17 feet in width or 15 feet 0 inches in height on highways and certain city streets. The Arkansas State Police often require escorts for loads that are particularly large or heavy.

For movements within Zinc, the Zinc Department of Transportation may mandate police escorts for oversize loads, especially during peak traffic hours. Scheduling these escorts requires advance notice, typically at least 68 hours prior to the move.

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

Required documentation for Zinc 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.

Zinc 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 Zinc Holiday Parade and the the Zinc Sports Tournament, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Zinc and areas around Zinc 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 Arkansas 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 Zinc, Zinc 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.
