To ensure the demanding FIA specifications for the track were met, GPS-based 3D paving equipment was used on the asphalt paving and milling machines. On June 13, 2012, Charlie Whiting-the FIA-appointed Race Director for Formula One-declared himself satisfied with the circuit's construction, scheduling a final pre-race inspection of the circuit for September 25, sixty days before the first race, which the circuit later passed. At the time of the announcement, the unstable clay soils under the road surface had caused Elroy Road to gradually buckle and shift, necessitating the upgrade.

FEMA issued a letter on June 28, 2011, stating the project meets its floodplain management criteria. Federal Emergency Management Agency (FEMA) declined to allow the project to move forward because part of the site lies in a floodplain.
The money was to be used to restore the land if the U.S. On January 21, 2011, a $900,000 check was posted with Travis County that permitted grading to begin. The first tasks were building the silt fences, taking core samples, and shredding existing vegetation. Following a stop-work order in December 2011, the completion date was revised to August. Construction began on December 31, 2010, and was due to be complete by June 2012. and Tilke Engineers & Architects designed the track, and Austin Commercial, a subsidiary of Austin Industries, was the general contractor.

On April 12, 2011, the track's name was announced as "Circuit of the Americas" at a press conference. McCombs wished to call the site "Speed City", but the owners originally anticipated selling the naming rights to various parts of the facility for $7 million. In the same news conference, Hellmund also revealed that Texas billionaire Red McCombs was the project's largest investor.
The majority of the site had been planned to be developed into a residential subdivision called "Wandering Creek".
In a news conference on July 27, 2010, Tavo Hellmund announced plans to build the track on about 890 acres (3.6 km 2) of undeveloped land in southeastern Travis County. The layout was conceived by promoter Tavo Hellmund and 1993 Motorcycle World Champion Kevin Schwantz with the assistance of German architect and circuit designer Hermann Tilke, who has also designed the Sepang, Shanghai, Yas Marina, Istanbul, Bahrain, Yeongam, and Buddh circuits, as well as the reprofiling of the Hockenheimring and Fuji Speedway. The circuit was the first in the United States to be purpose-built for Formula One. The circuit and Grand Prix were first proposed in the middle of 2010. It previously hosted the Australian V8 Supercars, the Americas Rallycross Championship, the American Le Mans Series, the Rolex Sports Car Series, the FIA World Endurance Championship, the IMSA WeatherTech SportsCar Championship and the Ind圜ar Classic. The facility is home to the Formula One United States Grand Prix, NASCAR's Texas Grand Prix, and the Motorcycle Grand Prix of the Americas, a round in MotoGP.
