All oversize loads entering the City of Mapleton, located in Monona County, must conform to the requirements set by the Iowa Department of Transportation (Iowa DOT) and the Mapleton Public Works Department.

In general, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, or exceeding the Iowa legal weight limits (typically 80,000 lbs gross weight) should obtain an oversize load permit from the Iowa DOT and potentially coordinate with the Mapleton Public Works Department for local routes.

The City of Mapleton, in conjunction with Monona County, prioritizes the safety and integrity of local infrastructure. Loads exceeding specific weight limits on County Road E34, particularly near the Maple Valley-Anthon Oto Community School, may require additional scrutiny and route adjustments to minimize impact on school traffic and road conditions.

In Mapleton, escort vehicles are typically required for loads exceeding 12 feet in width, 14 feet 6 inches in height, or 100 feet in length. Specific requirements depend on the route and potential obstructions.

Local police escorts are generally not required within Mapleton city limits unless the load presents an exceptional hazard or requires temporary road closures. If a police escort is deemed necessary, contact the Monona County Sheriff's Office well in advance to discuss fees and scheduling. Expect a minimum of $75 per hour with a 4-hour minimum.

Applicants must provide detailed information about the load, vehicle, route, and dates of travel. Documentation typically includes vehicle registration, insurance information, and a detailed description of the load.

Time-of-day restrictions are generally not enforced within Mapleton city limits unless the load poses a significant traffic hazard. However, avoid transporting oversize loads during peak school hours (7:30 AM - 8:30 AM and 3:00 PM - 4:00 PM) near the Maple Valley-Anthon Oto Community School.

Seasonal weight restrictions may be in effect during the spring thaw (typically March-April) to protect roadways from damage. Check with the Monona County Engineer's Office for current restrictions.

Avoid using residential streets whenever possible. Preferred routes should utilize Highway 175 and other major thoroughfares. Contact the Mapleton Public Works Department for guidance on the most suitable routes.

Permit fees for oversize/overweight loads in Iowa are determined by the Iowa DOT based on the dimensions and weight of the load, as well as the distance traveled. Base fees start around $25 and increase based on these factors.

Fees may be higher for loads requiring special routing, escorts, or temporary traffic control. Local fees from Mapleton are minimal, but any required police escort will incur additional costs from the Monona County Sheriff's Office.
