The Grand Prix of Long Beach threads through downtown streets and along the waterfront since 1975 — America's longest-running major street race. Formula 1 called it the United States West Grand Prix from 1976 through 1983; IndyCar and IMSA kept the barriers close and the pace brutal after F1 left. The 1.968-mile layout winds around the Long Beach Convention Center with a palm-lined start-finish straight and a famously tight final hairpin. This poster maps the temporary circuit as topography first — elevation ticks and contour dashes, not lap-record bragging.
