All oversize loads entering the City of Atwater, located in Merced County, must conform to the requirements set by the California Department of Transportation (Caltrans) and the City of Atwater Public Works Department.

Generally, any vehicle exceeding 8 feet 6 inches in width, 14 feet in height, or categorized as Class 8 (vehicles with a gross vehicle weight rating exceeding 33,000 lbs) should obtain an oversize load permit from the Atwater Public Works Department.

Loads traversing Highway 99 within Atwater city limits are subject to heightened scrutiny due to high traffic volume and require detailed route planning submitted with the permit application. Confirmation of bridge clearances along the route is also required to avoid any disruptions.

Escort vehicles are required in Atwater when the load exceeds 12 feet in width, 16 feet in height, or 120 feet in length. A lead and trail escort may be required for loads exceeding 14 feet in width, especially when navigating tight turns near downtown Atwater.

Local police escorts are required for loads exceeding 16 feet in width or 18 feet in height. Arrangements must be made at least 72 hours in advance through the Atwater Police Department Traffic Division. The current fee for a police escort is $75 per hour, with a minimum of 4 hours.

Certain residential areas and narrow streets within Atwater, such as those near Ralston Park, have restricted access for oversize loads. The permit will specify approved routes to avoid these areas. Loads are prohibited on Bellevue Road between Shaffer Road and Highway 99 during peak hours.

The base permit fee for an oversize load in Atwater is $50. Additional charges may apply based on the size and weight of the load, the distance traveled within city limits, and the need for escorts.

Fees are calculated based on a tiered system: loads exceeding 10 feet in width incur an additional $25 fee, and loads exceeding 14 feet in height incur an additional $50 fee. Mileage within Atwater is charged at a rate of $0.50 per mile for loads requiring police escort.
