Two problems with CS4 cycle superhighway

TfL are consulting on CS4. The video (below) shows the route in spring 2017 . Here are my comments on the now-published proposal

• the proposal would be greatly strengthened by negotiating a daytime route through Southwark Park. It is fortunate that peak usage of CS4 (by morning and evening commuters) does not coincide with peak usage of the park (lunch time, afternoons and weekends)
• CS4 should be extended at least to the east side boundary of Greenwich Park. Extending it may require some significant roadworks planning which could see the need for traffic cones to be placed in order to designate where the construction will occur and where members of the public need to avoid. Greenwich Town Centre is dangerous and unpleasant for cyclists and there is already a heavy flow of cyclists from Creek Road into Greenwich Park and from Greenwich Park to Central London. Many of these cyclists use the Greenwich Foot Tunnel and then CS3. This route is slow and awkward for cyclists while also causing conflicts with pedestrian use of the tunnel.

I appreciate thatTfL does not have authority to build cycle superhighways in parks but it can argue the case for such a route with Southwark Borough Council.
Apart from these two points I am fully in support of creating a superhighway on the A200.
