Book Truck and Trailer Parking in Sun Prairie, WI

• Interstate 94 (I-94) is the main east-west route into Sun Prairie, linking you with Milwaukee to the east and Madison to the west. Take Exit 244 for Highway N, then head north into town. U.S. Highway 151 runs north-south and connects Sun Prairie with Madison just southwest of the city before continuing north toward Fond du Lac. Wisconsin State Highway 19 runs east-west, connecting Watertown to the east and Waunakee to the west; it meets U.S. 151 and can be a calmer way to reach Sun Prairie. County Road N (Cty N) wraps around the city, crosses both I-94 and US 151, and gives you another way to move through the area on quieter roads. For reserved truck parking, these routes help you plan your approach before your hours run short. If you need 18-wheeler parking or semi truck parking, line up your turn early and watch for the last stretch from the highway to local streets, since that final approach matters when you're trying to stay legal under HOS.

For reserved truck parking in Sun Prairie, use the highway network to stay on the main commercial route and avoid last-minute lane changes. Traffic can tighten up during peak hours, and local roads may have height and weight limits that can put you in a bad spot fast.
