I visited the Austin F1 track site this morning, and was pleasantly surprised at the progress that has been made in the past couple of weeks. With the required permits apparently now in-place, a significant amount of work has been done on clearing and grading the site.
The following photos show progress to date. Please feel free to use the images, with accreditation to Ian Weightman. If you need high resolution or additional images please contact me through this blog or via Twitter @F1_AustinTX.
