All oversize loads entering the City of St. Charles, located in Madison County, must conform to the requirements set by the Iowa Department of Transportation.

In general, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, and within the Class B weight limits (over 80,000 lbs) should obtain an oversize load permit from the St. Charles Public Works Department in conjunction with the Iowa DOT.

Remember that St. Charles is primarily accessed via Highway 92 and County Road G14. Ensure your planned route avoids residential streets where possible and is pre-approved by the Public Works Department to minimize disruption to local traffic and residents, especially during school hours.

Escort vehicles are typically required in St. Charles when the load exceeds 12 feet in width, 14 feet 6 inches in height, or extends more than 10 feet beyond the front or rear of the transporting vehicle. Specific requirements will be detailed in your permit based on the route and load dimensions.

Local police escorts are generally not required within St. Charles unless specifically mandated by the Iowa DOT or the St. Charles Public Works Department due to exceptional circumstances, such as extremely wide loads or bridge clearances. If required, contact the Madison County Sheriff's Office to coordinate, and be aware that scheduling may require several days' notice and will incur an hourly fee per escort vehicle.

To apply for an oversize load permit for travel within St. Charles, you should first obtain the necessary Iowa DOT permit through their online system or by contacting the DOT directly. After that, contact the St. Charles Public Works Department at (641) 396-2221 to inform them of your route and request any necessary local permissions.

Documentation requirements include a copy of the Iowa DOT permit, vehicle registration, insurance information, and a detailed route map highlighting the proposed path through St. Charles. It's also helpful to include photos of the load being transported.

Time-of-day restrictions may apply during peak traffic hours, particularly between 7:00 AM and 9:00 AM and 4:00 PM and 6:00 PM on weekdays. These restrictions are designed to minimize traffic congestion during school drop-off and pick-up times.

Seasonal weight restrictions may be imposed on certain roads during the spring thaw to prevent damage to the pavement. Check with the Public Works Department for current restrictions.

Avoid routing through residential areas, especially on streets adjacent to the St. Charles Community Park and the elementary school. The use of Highway 92 and County Road G14 is strongly encouraged. Any route deviations must be pre-approved.

Permit fees for oversize loads in St. Charles are generally minimal, often waived if the Iowa DOT permit is in good standing and the route doesn't require significant coordination or traffic control. However, fees may be assessed for excessive use of city resources or for routes requiring special accommodations.

Fees can vary depending on the complexity of the route, the size and weight of the load, and the level of coordination required with local authorities.
