Fellas , It has come to my attention , that citylink has installed rear cameras on this new walkway that has been installed recently inbound just before Victoria St overpass . It also has extra purple lights on this tower and I suspect takes rear pictures for motorcycles etc. My guess is its being tested and commissioned for research into additional revenue raising , obviously. Its the only tower ATM that ive noticed that has this modification fitted. Next time you go by check it out and see if the rear flashes with a red glow at night like the current units do . Bastards
