There is now an official website. http://www.circuitoftheamericas.com/
The official announcement I believe is that MotoGP will also be using the track.
Austin will get another major motorsports event, a MotoGP race for 10 years beginning in 2013. The announcement was made Tuesday.
MotoGp is something of motorcycling’s answer to Formula One and has an international fan base. The Formula One track being constructed southeast of Austin is being designed to accommodate both F1 cars and motorcycles.
The circuit was officially named Circuit of the Americas. Click here for the circuit’s official website.
Also announced were plans for a three-story convention center that could be used year-round, and a trauma center that will be used as a training facility for area emergency care professionals and medical school students, officials said.
It will also have a large outdoor live music venue, promoter Tavo Hellmund said.
The announcement was made at a press conference this afternoon that featured Speed TV announcer Bob Varsha, investors Bobby Epstein and Red McCombs, 1993 MotoGP champion Kevin Schwantz and others.
Educational partnerships were also announced with Texas A&M, St. Edward’s and Huston-Tillotson universities as well as the Del Valle Independent School District.
In May, Austin was announced as the host city for the United States Grand Prix beginning in 2012. Construction is under way at the site near Austin-Bergstrom International Airport, and organizers hope to have it completed by June of next year.
The date of the first Formula One race has not been announced.
Here are some extra pictures I just found. The word is that the highly anticipated turn 1 is visible.
