The Heart of Route 66 Auto Museum is a natural stop on Sapulpa's stretch of the Mother Road, with classic cars, highway memorabilia, and one of the most photogenic giant gas-pump signs on Route 66. It leans into the romance of road travel without pretending the nostalgia is accidental.
It is a compact museum, but a good one if you are driving the historic route through Oklahoma. The displays work best as part of a wider Route 66 day, paired with downtown Sapulpa and nearby roadside architecture.
