Cyclists will hold a “go-slow” on Blackfriars bridge in central London before riding to the headquarters of Transport for London to call for more cycle-friendly policies.
The activists complain that streets have been redesigned in favour of cars at the expense of extra space for pedestrians, cyclists or public transport.
Andrew Tobert from eco-activist group Climate Rush said: “Imagine if cars were banned from central London. Buses would glide through town, people would feel safe cycling and our air would be clean. Children could walk to school. Instead, we have inefficiency.”
