As far as I have seen and can recall it is for pedestrians only, arguably it may or may not meet the definition of pedestrian street since its really just a wide footpath on either side (I am indifferent to the tagging), however bicycles are not permitted on the pedestrianised sections of George Street. Also will add to the south the tertiary section & pedestrian areas correctly mapped and up to date, the short north section to Ultimo Road is the only route permitted for motor vehicles (and cyclists for that matter)
