From Hackney Cyclists web-site:
A one-day experiment to make Cat & Mutton canal bridge car-free, as part of European Mobility Week.
Saturday 22nd September 2012
The canal bridge just south of Broadway Market, Hackney (plus the bridge approaches).
Who’s organising this?
Just for one day, we’d like residents and visitors to enjoy this section of street without a constant stream of motor traffic, and to consider the possibility of making the bridge permanently open to walking, cycling and buses only.
