All oversize loads entering Hammon, Oklahoma must conform to the requirements set by the Oklahoma Department of Transportation (OKDOT) and the Hammon Department of Transportation (HAMDOT).

In general, any vehicle over 11 feet in width, 13 feet 6 inches in height, and within the super heavy weight class (over 234,797 lbs) should obtain an oversize load permit from the OKDOT and potentially additional permits from HAMDOT.

To navigate the complexities of Hammon's infrastructure, it's crucial to plan routes that avoid sensitive areas like Hammon Convention Center and major construction zones along the Hammon Stadium area.

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

Required documentation for Hammon 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.

Hammon has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Hammon Winter Celebration and the the Hammon Music Show, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Hammon and areas around the Hammon Tunnel, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
