All oversize loads entering the City of Mamou, located in Evangeline 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, 16 feet in height, and within the super heavy weight class (over 200,001 lbs) should obtain an oversize load permit from the Mamou Public Works Department.

Mamou has specific regulations to ensure the safe passage of oversized loads through its historic downtown area and residential neighborhoods, with particular attention to the city's narrow streets and potential roadwork.

In Mamou, escort vehicles are required for loads exceeding 14 feet in width or 18 feet in height. The escort must be provided by a licensed escort service and must be equipped with the necessary safety equipment, including amber lights and flags.

For loads that require a police escort, arrangements must be made through the Evangeline Parish Sheriff's Office or the Mamou Police Department at least 48 hours in advance. Fees for police escorts vary based on the duration of the escort and the number of officers required.

To apply for an oversize load permit in Mamou, applicants must submit their request through the Louisiana Department of Transportation and Development's online permit portal or by contacting the Mamou Public Works Department directly.

Applicants must provide detailed information about the load, including its dimensions, weight, and proposed route through the city. Additional documentation, such as proof of insurance and a detailed route survey, may also be required.

Mamou has time-of-day restrictions for oversize loads, prohibiting their movement during peak traffic hours (7-9 am and 4-6 pm) on weekdays.

During periods of heavy rain or flooding, oversize loads may be restricted from traveling on certain routes, particularly those that are prone to flooding or have been designated as flood evacuation routes.

Certain neighborhoods and historic districts within Mamou have restricted access for oversize loads due to narrow streets and potential damage to historic infrastructure.

The standard permit fee for oversize loads in Mamou is $150, with additional fees based on the complexity of the route and the need for specialized escorts or road closures.

For super heavy loads (over 200,001 lbs), an additional fee of $200 is applied to cover the costs of road reinforcement and monitoring.
