Where Was Ontario Motor Speedway?

As a child growing up in the 1970’s one of my fondest memories is that of Ontario Motor Speedway.  Although I had never been there, my family and I drove past it countless times as we drove to our weekly campouts usually in the Victorville or Barstow area.  
 
I can remember reading what the Ontario Motor Speedway “Big O” electronic sign said each week as we approached the then, incomplete Interstate 10 and Interstate 15 interchange with it’s onramps to nowhere towering what seemed like hundreds of feet over I10.  I was even the proud owner of a Sizzlers “Fat Track” Big-O racetrack toy that was modeled after Ontario Motor Speedway.
 
I never attended any races at the speedway, and was too young to go to any of the 3 Cal Jam concerts held there, but I never forgot the raceway or that freeway sign.

Now 40 years after those fond memories I find myself living right up the street from the old racetrack site, and my wife works literally across the street from the location, but I still did not know the exact location, size and configuration of the old raceway.  I remember reading news reports when the Ontario Mills Mall was being built that it was constructed “in the footprint of Ontario Raceway”, and I remembered that it was north of the 10 Freeway, around Haven Ave or Milliken Avenue, but the exact location and layout of the racetrack was still a mystery.  I assumed that the round, racetrack shape of Ontario Mills was the racetrack infield.

Not Auto Club Speedway

Many people confuse what was Ontario Motor Speedway (The Big “O” racetrack) with the newer California Speedway only two miles away in Fontana. The Fontana racetrack, known as Auto Club Speedway or California Speedway was built 17 years after the last bits of Ontario Motor Speedway were torn down.

There is not a lot of information on the internet about Ontario Motor Speedway but after doing a bit of research, finding some old maps, and watching this great video from Rusting Relics, I was able to plot the exact location of the Speedway and create these map overlays that show the exact location and layout of the racetrack and what is there today.  If you spot any errors please post a comment below.
 

Where Ontario Motor Speedway Was, And What Is There Now:

The speedway was bordered on the north by 4th Avenue (then referred to as San Bernardino Avenue), on the south by Interstate 10, the west by Haven Avenue, and the east by Milliken Avenue, which still has the eastward curve needed to make room for turn 1 and turn 2 of the racetrack.   Milliken Avenue is one of (maybe the only) street with curves like this in the entire city. 

Contrary to those news reports about the Ontario Mills Mall being built inside the old racetrack, this is not the case.  Ontario Mills Mall lies across the street, due-east of what was the racetrack, on the east side of Milliken Avenue.  When the Speedway was still in existence, the future home of Ontario Mills Mall was either empty fields, or parking areas, depending on the year. 
 
Even though virtually nothing remains of the race track, other than some of the raised-burms that made turn number 3 at the corner of 4th and Haven Avenues, The City Of Ontario has retained some of the history and heritage of the racetrack by building Ontario Motor Speedway Park a few blocks west of the racetrack site and by using auto racing inspired street names in and around the old speedway.  Let’s give Ontario some credit for these street names!
  • Jaguar Way

  • Corvette Dr

  • Triumph Ln

  • Shelby St.

  • Concours St.

  • Lotus Ave.

  • Porsche Way

  • Mercedes Ln

  • Duesenberg Dr.

  • Ferrari Ln.

Do you collect items from the Big "O" ?

Just memories Bill !

I have the best memories at Ontario Motor Speedway back in the day. My mother worked there from the day it opened to the day it closed down, very sad day.

HI GREG!! What’s your Mom’s name, I might have known her. I worked for the executive office of the Speedway (on Wilshire in L.A.) and attended all the races, got to hang out in the suites, pits, etc. Had a blast. Met so many wonderful people. It was so sad when they tore it down. :)

Where did everybody park their cars? The only person I know that ever went to a race said he had to take a bus!

The main parking lot was located on the south side of the track, just north of the 10 freeway. The fields on the north, east, and west of the track were also used for parking.

Our Father took us to a race when it was open don’t remember the year I must have been around 10 I think and I was born in 1964. We had seats towards the end of turn 1 and I could swear that we parked in the parking lot behind the main straight away. I was young but I remember that day as very well and how excited I was when we got there.

There were parking areas south of main grandstand / front stretch and turns one and two. Maybe three and four too. The speedway was constructed on vineyard property located adjacent of the San Bernardino Freeway I-10. There is a interesting Facebook group which includes many photos and stories on the late, great OMS.
The group on Facebook is: Ontario Motor Speedway and More.
Check it out.

Fond memories ! We used to go there on the 4th of July, lots of people would do their fireworks there ...miss those old days.

Jerry Garcia was scheduled to perform here on
5/27/73 with the Grateful Dead. The Allman Brothers were also on the bill. This show was cancelled.
