Cycling in Melbourne Australia
Meanwhile, several years later:
Since 1992 private motor vehicles have been restricted from accessing Swanston between 7am and 7pm. From midnight 20 May 2011, the existing restrictions will extend to 24 hours, seven days a week. Strictly no private motor vehicles are permitted to enter Swanston Street between Flinders and Latrobe Streets from 20 May 2011.
Today Swanston Street, tomorrow the world ;-)
As for walking bike past construction works, when are motorists ever expected to push their cars past road works? :-/
