All oversize loads entering Hardin, Kentucky must conform to the requirements set by the Kentucky Department of Transportation (KYDOT) and the Hardin Department of Transportation (HARDOT).

In general, any vehicle over 11 feet in width, 13 feet 6 inches in height, and within the super heavy weight class (over 257,326 lbs) should obtain an oversize load permit from the KYDOT and potentially additional permits from HARDOT.

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

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

The Hardin Department of Transportation requires a minimum of 32 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Hardin.

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

Required documentation for Hardin 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.

Hardin 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 Hardin International Show and the the Hardin Heritage Convention, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Hardin and areas around the Hardin Financial 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 Kentucky 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 Hardin, Hardin 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.
