All oversize loads entering Puget Island, located in Wahkiakum County, must conform to the requirements set by the Washington Department of Transportation.

In general, any vehicle over 12 feet in width, 14 feet in height, and within the super heavy weight class (over 105,000 lbs) should obtain an oversize load permit from the Wahkiakum County Public Works Department, as Puget Island falls under their jurisdiction.

Additionally, loads exceeding 18 feet in width, 18 feet in height, or weighing over 200,000 lbs require special permits and may need to follow specific routes to avoid low bridges and weak road structures, such as those found on Puget Island's rural roads.

In Puget Island, escort vehicles are required for loads exceeding 16 feet in width or 14 feet in height during daylight hours, and for any oversize load at night. Escort vehicles must be equipped with appropriate warning lights and flags.

For loads wider than 20 feet or taller than 18 feet, a police escort may be required. The Wahkiakum County Sheriff's Office is responsible for providing escorts, and arrangements must be made at least 48 hours in advance. Fees for police escorts vary based on the time of day and the number of officers required.
