All oversize loads entering Subiaco, Arkansas must conform to the requirements set by the Arkansas Department of Transportation (ARDOT) and the Subiaco Department of Transportation (SUBDOT).

In general, any vehicle over 11 feet in width, 15 feet 0 inches in height, and within the super heavy weight class (over 163,983 lbs) should obtain an oversize load permit from the ARDOT and potentially additional permits from SUBDOT.

To navigate the complexities of Subiaco's infrastructure, it's crucial to plan routes that avoid sensitive areas like Subiaco Hills and major construction zones along the the Subiaco Harbor area.

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

The Subiaco Department of Transportation requires a minimum of 64 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Subiaco.

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

Required documentation for Subiaco 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.

Subiaco has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Subiaco Winter Fair and the the Subiaco International Festival, which may impact routing and scheduling.

Certain neighborhoods, such as Subiaco Center and areas around the Subiaco River, 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 Subiaco, Subiaco 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.
