(CNN) -- In response to a crash during a February race at the Daytona International Speedway that injured dozens of spectators in the stands, officials at the track will add cables on crossover gates and tether the frames of the gates to posts in time for NASCAR races in July, representatives for the Florida speedway said Wednesday.
Changes were also made at Talladega Superspeedway in Alabama, where events will be held this weekend. The 2.67-mile track is known as one of the fastest on the NASCAR circuit.
There are seven crossover gates, a part of the massive metal fence that opens to allow people to cross the racing surface, at each track, officials said.
On February 23, a jaw-dropping wreck occurred on the last lap of the Nationwide Series race when Kyle Larson's car went airborne and pieces of his car flew into the grandstands. At least 28 people were injured, officials said.
