All oversize loads entering the City of Maryville must conform to the requirements set by the Tennessee Department of Transportation (TDOT) and Blount County regulations.

In general, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, or carrying a load classified as a Super Load (over 200,000 lbs) should obtain an oversize load permit from the Maryville Public Works Department, in coordination with TDOT.

Specifically, loads traversing Alcoa Highway (US-129) within Maryville city limits must adhere to strict weight limits due to bridge infrastructure. Coordinate closely with TDOT Region 1 for pre-approved routes and weight restrictions on this corridor.

Escort vehicles are required in Maryville when loads exceed 12 feet in width, 14 feet 6 inches in height, or 100 feet in length. Front and rear escort vehicles are mandatory for loads exceeding 14 feet in width or 110 feet in length.

Local police escorts through the Maryville Police Department are required for any load exceeding 16 feet in width or 150 feet in length. Fees for police escorts are $75 per hour, per escort, with a minimum of 4 hours. Scheduling requires at least 72 hours advance notice through the Maryville Police Department's Traffic Division.

To apply for an oversize load permit in Maryville, you must first obtain a permit from TDOT. Once you have the TDOT permit, you can apply for a local permit through the Maryville Public Works Department. Applications can be downloaded from the City of Maryville website (www.maryville-tn.gov) under the Public Works section, or obtained in person at City Hall (400 W. Broadway Ave, Maryville, TN 37801).

Documentation requirements include a copy of the TDOT permit, vehicle registration, insurance information, a detailed route plan within Maryville, and a description of the load. For loads impacting state routes within the city, TDOT's approval is paramount.

Time-of-day restrictions are in effect in Maryville. Oversize loads are prohibited from traveling on major thoroughfares, including Alcoa Highway (US-129) and Broadway Avenue (US-321), between the hours of 7:00 AM - 9:00 AM and 4:00 PM - 6:00 PM, Monday through Friday, due to peak traffic volume.

Seasonal weight restrictions may be imposed on certain city streets during the spring thaw (typically March and April) to prevent road damage. Check with the Public Works Department for current restrictions.

Certain residential neighborhoods, particularly in the downtown area and near Maryville College, have restricted routes due to narrow streets and low-hanging utility lines. Pre-approved routes will be specified on the permit.

The base permit fee for oversize loads in Maryville is $50.00. Additional charges may apply based on load dimensions, weight, and the length of the route within the city.

Loads requiring police escorts are subject to the Maryville Police Department's hourly escort fee, as mentioned above. A supplemental fee of $25 will be added for routes longer than 10 miles within the city limits.
