Last week ACC installed a shared path (cyclists & pedestrians) on North Terrace. It is at the end of Pulteney Street and about as wide. There are signs (outlines of pedestrian & cyclist) attached to street furniture. The purpose is to assist those who cycle to studies or work at University of Adelaide. ACC has kindly provided a map.

The signage actually points the wrong way giving the false impression that its legal to ride along the northern footpath further west and east of that short section. I do it anyway as there are so many road entrances into and out of the Uni/Museum/Art Gallery that the footpath is effectively just a pile of driveways stuck together
Before I moved buildings I used to ride along North Terrace footpath to get from the Frome/NT traffic lights to the UofA underground bicycle cage. It is wide and perfectly safe if you don't go too fast.
I walked by there today. It’s great to see the council responding to a problem which NTPBUG engaged with council over on several occasions. It would seem they still need to add some paint markings and light signals. Yes it makes riding the bike legal at least over North Terrace. Cyclists should yield to pedestrians as they make their way in to the Uni.
