Video: Austin track construction time-lapse for July

As seen from Turn 1, the grandstand subgrade preparation has begun, the paddock building base material has gone down and pier drilling for the pit building can be seen. Subgrade work under the track areas continues. The track contours are visible and major infrastructure features such as tunnels, drainage and retention facilities are in place. Preparation is under way for vertical construction including the grandstands, and pit and paddock buildings.
