The Challenge Miami Triathlon will be closing County Road 905 and Card Sound Road traffic from 6:30 a.m. to 1 p.m. on Sunday, March 14.
Residents and workers at Ocean Reef as well as other locals, including delivery drivers, will be able to use County Road 905, but not Card Sound Road during those times.
All motorists will take the 18-Mile Stretch as a detour during those times.
Racers will leave the Homestead-Miami Speedway and eventually head south on Card Sound Road to Alabama Jacks and turn around, heading back to the race track.
