All oversize loads entering the City of Palmyra, located in Marion County, must conform to the requirements set by the Missouri Department of Transportation.

In general, any vehicle over 12 feet in width, 14 feet 6 inches in height, and within the Class 6 weight category (over 80,000 lbs but not exceeding 90,000 lbs for divisible loads with a permit) should obtain an oversize load permit from the Palmyra Public Works Department.

The City of Palmyra adheres to the regulations outlined by the Missouri Department of Transportation for oversize and overweight vehicles. Loads exceeding these dimensions require special permits and may need to follow specific routes to avoid infrastructure damage and minimize traffic disruption.

In Palmyra, escort vehicles are required for loads exceeding 16 feet in width, 18 feet in height, or 150 feet in length. The escort vehicle must be equipped with appropriate warning lights and signage as per Missouri state regulations.

For oversize loads, the escort vehicle must be positioned ahead of the load to warn oncoming traffic. Local police escort may be required for particularly large or complex loads, and arrangements must be made in advance with the Marion County Sheriff's Department. Fees for police escorts vary based on the complexity of the move and the number of officers required.

To apply for an oversize load permit in Palmyra, applicants can submit their application through the Missouri Department of Transportation's online permitting system or contact the Palmyra Public Works Department directly. Required documentation includes the load's dimensions, weight, and intended route through the city.

Applicants must also provide proof of insurance and a detailed description of the cargo being transported. For complex or oversized loads, a route survey may be required to identify any potential restrictions or necessary accommodations.

Oversize loads are not permitted to travel through Palmyra during peak traffic hours (7-9 am and 4-6 pm, Monday through Friday) unless specifically authorized by the Palmyra Public Works Department.

Seasonal restrictions may apply during periods of heavy rainfall or flooding, which can impact the weight and size limits on certain city roads. It is the responsibility of the permit holder to check with the City before embarking on their journey.

Certain streets within Palmyra's historic district have restricted access for oversize loads. Permittees are required to follow designated routes to avoid these areas.

The base permit fee for oversize loads in Palmyra is $50. Additional fees apply based on the size and weight of the load, as well as the complexity of the route. For example, loads requiring a police escort incur an additional $200 fee.

Permits for loads exceeding standard dimensions (12 feet wide, 14 feet 6 inches high, or 80,000 lbs) are subject to a tiered fee structure, with fees ranging from $100 to $500 or more, depending on the extent of the oversize dimensions.
