The Beverly Hills Speedway opened on February 28, 1920 on a lot bounded by Wilshire Blvd, South Beverly Dr, Olympic Blvd, S. Lasky Dr. It was a wood-boarded, oval-shaped race track with seating for an impressive 70,000 race fans. It was only around for 4 years – the final race was held February 24, 1924. It was very popular in its day, but good luck finding your car afterward. You’d be okay if the roof of yours was white, otherwise you’d be smart to allow a couple of extra hours at the end of the day.
Here is a photo I found showing the location of the Beverly Hills Speedway. (It’s a bit misleading, though, as the Beverly Wilshire Hotel faces north, not south as pictured here. But I’m sure you get the idea.)
This is how that land looks today—wall to wall housing. It’s why the Speedway didn’t last too long: that land got way too valuable to use it driving cars around in a circle.
