Additional Information
The Spokane River cuts right through the heart of Post Falls, and Falls Park remains one of the most photographed spots in Kootenai County. From Treaty Rock Park to the trails along Black Bay, residents here tend to build their weekends around water and pine-scented air. Knudtsen Chevrolet sits on East Polston Avenue, well positioned for drivers coming off Interstate 90 whether they live in downtown Post Falls or commute from Rathdrum and Hayden to the north. Families who spend summer afternoons at Q’emiln Park or hike the Post Falls Community Forest often appreciate having a established dealership close to home rather than crossing into Washington. The North Idaho Centennial Trail threads through the city as well, connecting cyclists and runners toward Coeur d’Alene and beyond. For a community that balances small-town character with rapid growth, Knudtsen Chevrolet has become a familiar name along one of the Inland Northwest’s busiest corridors.
