No, the ride will be on open roads for the majority of the time.
South Australia Police will be escorting all riders from the start for a short distance. However this escort does NOT represent a road closure and riders MUST obey all normal road rules, including stopping at any red traffic signals, railway crossings, stop signs, riding two abreast and obeying the instructions of SAPOL or any Bupa Challenge Tour official or marshal.
However, during the ride the Southern Expressway will be closed to traffic. No cyclists will be able to enter until the official lead vehicle has entered first. After the ride, the expressway will be closed to all cyclists.
