NASCAR is adding more soft walls beyond Daytona International Speedway.

International Speedway Corp., NASCAR's sister company that owns Daytona and several other sanctioned tracks, announced plans Saturday to install about 54,000 feet of additional energy-absorbing SAFER Barrier at its facilities. That total includes the 4,100 feet recently installed at Daytona and the 4,000 feet track officials have planned following Sunday's race.

ISC President John Saunders says the decision to add more "soft walls" came as a result of a thorough review and audit of impact-absorbing technologies at tracks. Saunders says ISC will work with Cheaha Construction, Smith Fence Company, and North Industrial Machine to install the walls.

He adds that "as safety remains at the forefront, ISC will continue to work with NASCAR to evaluate specific locations inside the turns for future safety enhancements."
