Vertical construction begins in Austin

Work at the 2012 US grand prix venue in Austin is back at full swing, according to the motoring weblog Jalopnik.

"The crews are on site and construction of the Circuit of the Americas is underway. I saw it with my own eyes," wrote the reporter.

The news follows the recent contractual disagreement between the circuit owners, original promoter Tavo Hellmund and Bernie Ecclestone that almost steered the entire project off track.

"Last month the track was mostly just a collection of cleared dirt paths but now crews on every part of the track are working to establish the necessary support structures," the reporter revealed.

"Cranes hold the support beams for the pits, paddock, and media centre."

The Texas venue’s communications boss Ali Putnam confirmed that the project is "back to normal" after the speedbump.
