All oversize loads entering Washington, Louisiana, 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 3 weight category (over 120,000 lbs) should obtain an oversize load permit from the Washington Public Works Department or directly through the Louisiana Department of Transportation and Development.

Additionally, loads exceeding these dimensions or weight classifications must adhere to specific routing and scheduling guidelines to minimize disruptions to local traffic and infrastructure.

Escort vehicles are required in Washington for oversize loads exceeding 16 feet in width or 18 feet in height. Escorts must be provided by certified escort vehicle operators.

For loads that traverse through downtown Washington or utilize major highways such as US-190, police escorts may be required. Arrangements for police escorts should be made through the Washington Police Department with at least 48 hours' notice, and may incur additional fees based on the duration and complexity of the escort.

To apply for an oversize load permit in Washington, applicants can visit the Louisiana Department of Transportation and Development's website or contact the Washington Public Works Department directly. Required documentation includes detailed load specifications, proposed route, and travel times.

Applicants should be prepared to provide documentation such as load diagrams, vehicle registration, and insurance certificates.

Oversize loads are restricted from traveling through downtown Washington during peak hours (7-9 am and 4-6 pm) on weekdays.

Travel is also restricted during major local events such as the Washington Parish Free Fair, typically held in late October.

Certain neighborhoods like Historic Downtown Washington may have restricted routes or require special permits for oversize loads.

The standard permit fee for oversize loads in Washington is $50, with additional fees ranging from $25 to $100 based on the complexity of the route and the need for escorts or special accommodations.

For example, routes that require the use of utility poles or road closures may incur higher fees due to the need for additional infrastructure assessments and coordination with local utilities.
