cooperation with other associations is often required. for example, the two bridges leading into the cbd are controlled by the sydney harbour foreshore authority (pyrmont bridge), and the rms (sydney harbour bridge). the nsw government, through the rms, control all traffic lights (including along cycleways), arterial roads and speed limits. although there are plans to limit major cbd roads to private cars, on-going efforts to make the city more friendly to non-motorised transport are made through agreements with the nsw state government.
