Martinsville Speedway will erect additional tire barriers in time for this weekend's NASCAR races.
International Speedway Corp. said Monday the tire barriers will be installed at the end of the backstretch of the .526-mile oval. The barriers will be in place in time for Sprint Cup practice and qualifying on Friday.
All tracks that host NASCAR events are studying their safety measures following Kyle Busch's crash last month at Daytona. Busch broke his right leg and left foot in the Xfinity Series opener when he spun and hit a concrete wall that was not protected by an energy-absorbing SAFER barrier.
