All oversize loads entering the City of Coalmont in Grundy County must conform to the requirements set by the Tennessee Department of Transportation (TDOT) and Coalmont's local ordinances.

Generally, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, or exceeding 80,000 lbs gross vehicle weight requires an oversize/overweight permit from both TDOT and potentially the Coalmont Public Works Department if local roads are utilized.

Loads traversing Main Street (Highway 56) require special consideration due to older infrastructure. Contact the Coalmont Public Works Department at (931) 692-3471 to coordinate routes and ensure bridge weight limits are not exceeded, particularly for loads exceeding 100,000 lbs.

Escort vehicles are typically required in Coalmont for loads exceeding 12 feet in width, 14 feet in height, or 100 feet in length. Specific escort requirements are determined on a case-by-case basis by TDOT and may be influenced by the chosen route within Coalmont.

Local police escorts are generally not required within Coalmont unless specifically mandated by TDOT or the Coalmont Public Works Department due to unusual load characteristics or route complexities. If required, arrangements must be made at least 72 hours in advance through the Grundy County Sheriff's Department at (931) 692-3466. Fees for police escorts are typically $75 per hour with a 4-hour minimum.

Permits for oversize/overweight loads are primarily obtained through the Tennessee Department of Transportation's online permitting system. Access the system and relevant information at the TDOT website (www.tn.gov/tdot). For loads impacting Coalmont local roads, contact the Coalmont Public Works Department to confirm routing and any local requirements.

Required documentation typically includes vehicle registration, insurance information, load dimensions and weight, a detailed route plan, and any relevant engineering certifications for specialized loads. Be prepared to submit axle weight distribution details to ensure compliance with bridge weight limits.

Time-of-day restrictions may apply to loads traveling through Coalmont, particularly during school hours (7:00 AM - 8:30 AM and 2:30 PM - 4:00 PM) near Coalmont Elementary School on Main Street. Check with the Coalmont Public Works Department for specific restrictions.

Seasonal weight restrictions may be imposed on certain roads during the winter months (December - March) to protect road surfaces from damage due to freeze-thaw cycles. Contact the Grundy County Highway Department for current restrictions.

Avoid routing loads through residential areas whenever possible. Consult with the Coalmont Public Works Department to identify preferred routes that minimize disruption to local residents. Note that Highway 108 outside Coalmont has some narrow sections and sharp turns that require careful planning.

TDOT permit fees are based on load dimensions, weight, and distance traveled. Expect base fees to start around $25, with additional charges for overweight or overdimensional loads. Consult the TDOT website for the latest fee schedule.

Fees may vary significantly based on the gross weight of the load and the number of miles traveled on state routes. Local fees from Coalmont are unlikely unless specific services like traffic control are required.
