Construction crews this past week installed additional SAFER barriers along the inside wall of the Las Vegas Motor Speedway back straightaway.
Earlier this year, Jeff Gordon made wrecked in the area that is now protected by the SAFER barrier.
"Following this year's Cup (race) we consulted with NASCAR officials and our own engineers. We all agreed that installing the barrier on the backstretch was the proper course of action," said track general manager Chris Powell.
The new barrier covers 1,700 feet of the inside backstretch wall. SAFER barriers now cover 7,800 feet of the retaining walls around the 1.5-mile superspeedway.
