This will be a brand new 3.7 mile road course that is being built in Oak Ridge Tennessee (near Knoxville TN). The 900 acre facility used to be the Ole Manhattan Project which is where the Atomic Bomb was made during WWII. Now it will be home for a Motorsports park with 34 turns and a loooong backstretch. Oak Ridge has made an impact on Motorsports around the world including the research and development of the carbon brake rotors that are standard equipment on Formula 1 race cars and MotoGP motorcycles.
