All oversize loads entering Westport, Washington must conform to the requirements set by the Washington Department of Transportation (WADOT) and the Westport Department of Transportation (WESDOT).

In general, any vehicle over 12 feet in width, 14 feet 0 inches in height, and within the super heavy weight class (over 245,142 lbs) should obtain an oversize load permit from the WADOT and potentially additional permits from WESDOT.

To navigate the complexities of Westport's infrastructure, it's crucial to plan routes that avoid sensitive areas like Westport Research Park and major construction zones along the Westport Historic District area.

Westport has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-9 am and 4-6 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Westport International Exhibition and the the Westport Film Fair, which may impact routing and scheduling.

Certain neighborhoods, such as Westport Center and areas around the Westport Financial Center, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
