This campaign started back in 2011 and there doesn't seem to be any mention of it here on Archiseek (apart from my own posts).
There was a meeting in the Mansion House hosted by Lord Mayor Andrew Montague last Monday (2nd April 2012) regarding the proposal.
It is proposed that the folowing areas be closed to traffic on a trial basis for 6 months:
Upper Drury Street,
South William Street,
St. Stephens Green (top of Grafton Street)
Green: Current pedestrian zones
Blue: To be closed to traffic
Pink: Car park access

Perhaps the presentation isn't as professional as Dublin Civic Trust ;-), but I think it should be welcomed.
What do Archiseekers think? Better left to the professionals? Let's face it, DCC need all the help they can get.
