All oversize loads entering the City of Madisonville, located in St. Tammany Parish, must conform to the requirements set by the Louisiana Department of Transportation and Development (DOTD).

In general, any vehicle over 12 feet in width, 14 feet 6 inches in height, and within the Class 8 weight category (over 91,000 lbs) should obtain an oversize load permit from the Madisonville Public Works Department.

The permit process involves submitting detailed route information and load specifications to ensure compliance with local and state regulations, particularly to avoid damage to the city's infrastructure and minimize disruptions to the community.

In Madisonville, escort vehicles are required for oversize loads exceeding 16 feet in width or 18 feet in height, or when the load is over 150 feet in length. Escort vehicles must be equipped with appropriate warning lights and flags.

For loads requiring a police escort, arrangements must be made through the St. Tammany Parish Sheriff's Office. The escort service must be scheduled at least 48 hours in advance, and fees will be based on the actual time used, with a minimum charge of $150.

To apply for an oversize load permit in Madisonville, applicants must submit their request through the Louisiana Department of Transportation and Development's online permit portal or by contacting the Madisonville Public Works Department directly at (985) 216-5100.

Documentation required includes detailed load dimensions, weight, and route information, as well as proof of insurance and a valid USDOT number. For loads traveling through the city's historic district, additional documentation may be required to ensure compliance with local preservation regulations.

Oversize loads are restricted from traveling through Madisonville during peak traffic hours (7-9 am and 4-6 pm, Monday through Friday) unless specifically permitted by the Madisonville Public Works Department.

Seasonal restrictions may apply during periods of heavy rainfall or when road conditions are deemed hazardous by the St. Tammany Parish Government. Loads must also avoid certain neighborhoods, such as the Lakeshore Drive area, due to narrow streets and residential traffic.

The base permit fee for oversize loads in Madisonville is $75, with additional charges based on the complexity of the route and the size of the load. For example, loads requiring a police escort will incur an additional fee of $150, plus $50 per hour for each hour over the initial 2 hours.

Fees also vary based on the weight class of the load, with Class 8 loads (over 91,000 lbs) incurring a surcharge of $200.
