Formula 1 race director Charlie Whiting visited the Circuit de the Americas ahead of this year's United Stated Grand Prix.
The 3.4-mile circuit is scheduled to host its inaugural race on November 18, and work is continuing on in order to have the track ready in time.
Whiting visited the circuit after the Canadian Grand Prix to monitor its progress, and he was happy with the progress.
He will return for the final pre-race inspection in September.
"It is clear that the significant resources Circuit of the Americas has committed to completing this facility on time and to FIA specifications is making a difference," Whiting said.
"The more than 500 construction workers on site daily are making great progress, and I plan to return to Austin at the end of August for an update.
"My formal pre-race inspection is set for September 25, which is 60 days before the scheduled start of the United States Grand Prix."
