Which former Route 66 service station in Rancho Cucamonga now houses a local history museum?

The Cucamonga Service Station in Rancho Cucamonga, California, now houses a local history museum.

The service station was built in 1915, before Route 66 was designated as a federal highway. Its survival gives visitors a glimpse of early automobile travel and the roadside businesses that later became associated with the Mother Road.

After restoration, the building became a museum devoted to Route 66 and the surrounding area. Its design reflects the small-scale filling stations that served motorists before large modern fuel plazas became common.

Rancho Cucamonga lies in Southern California along the historic corridor between Los Angeles and the desert. The station is an example of how preservation groups have reused surviving commercial buildings rather than treating Route 66 only as a roadbed. Its earlier construction date also shows that some Route 66 landmarks began serving travelers before the highway received its official number.
