The Cucamonga Service Station is a historic gas and automobile service station located in Rancho Cucamonga, California. Local lore claims it was built in 1915 by Henry Klusman, who built many of the early buildings in Cucamonga, but no documented evidence of this has been yet discovered. The station operated until 1971. In 1926, the historic U.S. Route 66 was organized, and the station sits on the North side of the Route 66. The Cucamonga Service Station was originally one of thousands of similar service stations along the route. Today, it is the only surviving service station of its design on Route 66 in California.
