A great documentary about Greater London Councils cycling infrastructure improvements in the early 1980s.
Covers policy, implementation and vision. Whatever someone’s politics it is interesting to imagine where UK cycling policy may have been today if the cycling unit and "Livingston's" GLC had not been abolished in 1986.
Although Boris Johnston and the GLA is doing good work from the Superhighways to "Boris bikes" what happened in the early 1980s must have been quite ground breaking at the time if the momentum had been maintained cycling infrastructure may have been much enhanced today.
A report that highlights some of the trends in both cycling and policy.
