The estimated cost of delivering the two pilot Cycle Superhighways routes is £22m. The work on the first two routes will help TfL determine in detail the scope and cost of the Cycle Superhighways. TfL will test new interventions on the pilot routes, and monitor their effectiveness. This will determine the future cost of the whole programme.
At a cost of £22m for two pilot superhighways.
