Road Closures

Roads proposed to be closed along the IRONMAN 70.3 bike course will be considered soft closures, meaning vehicle traffic will be allowed to flow in both directions within the closure IF it originates from within the closed area. Additional traffic from outside the closed area will be directed to use detours. The goal of these closures is to reduce overall traffic conflicts and improve the safety for the motoring public and athletes.
