All oversize loads entering the City of Allen, located in Pontotoc County, must conform to the requirements set by the Oklahoma Department of Transportation (ODOT).

In general, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, and exceeding 80,000 pounds in gross vehicle weight should obtain an oversize load permit from the Allen Public Works Department, in conjunction with ODOT regulations.

Specifically, loads traversing State Highway 1, which runs through Allen, must adhere to stricter weight limits during spring thaw (typically February-March) to protect the pavement. Check with ODOT for current restrictions.

Escort vehicles are required in Allen when the load exceeds 12 feet in width, 14 feet 6 inches in height, or 100 feet in length. Front and rear escorts are typically required for loads exceeding these dimensions, especially on two-lane roads like County Road N3680.

Local police escorts are not generally required within Allen city limits unless specifically mandated by ODOT or the Allen Public Works Department due to unusual circumstances. If required, contact the Allen Police Department non-emergency line at (580) 668-3311 to inquire about availability and associated fees, which are typically $75 per hour per officer, with a 4-hour minimum.

To apply for permits in Allen, first obtain the necessary ODOT permits through their online permitting system. Then, contact the Allen Public Works Department at (580) 668-3221 to inform them of the ODOT permit and the planned route through Allen. While Allen doesn't typically require its own permit, they need notification to ensure route suitability.

Documentation requirements include a copy of the ODOT permit, a detailed route plan showing entry and exit points from Allen, and a certificate of insurance. Providing accurate axle weights and dimensions is crucial for approval.

Time-of-day restrictions are generally not enforced within Allen, except during school hours (7:30 AM - 8:30 AM and 3:00 PM - 4:00 PM) near Allen Public Schools. Avoid transporting oversized loads near school zones during these times.

There are no specific seasonal restrictions in Allen beyond ODOT's statewide regulations. However, be aware of potential flooding along Muddy Boggy Creek during heavy rainfall, which could impact certain routes.

Avoid routing oversized loads through residential areas, particularly the older neighborhoods near downtown Allen. The preferred route is generally along State Highway 1, minimizing turns onto local streets.

The City of Allen does not typically charge a separate permit fee for oversize loads as long as ODOT requirements are met. However, fees may apply if a police escort is required, as detailed in the Escort Requirements section.

Keep in mind that ODOT's permit fees will vary significantly based on load size, weight, and distance traveled within Oklahoma.
