Daytona and Talladega Superspeedway announced Wednesday that the high-banked tracks are installing additional cables at the crossover gates, which allow fans to move between the grandstands and the infield before and after races. The tracks also are adding supplemental tethers between the gate frame and support posts.
One of the eight gates at Daytona was where rookie Kyle Larson crashed on the final lap of the second-tier race the day before the Daytona 500. Larson's car went airborne, slammed into the fence and spewed debris into the stands.
Larson was unharmed. Daytona repaired the fence before the 500, and then hired a structural engineering firm to review the fence and propose improvements.
