 The group voiced concerns that there were a number of "pinch points" (sections of road not wide enough to accommodate two lanes of traffic and two tram lanes) along the Uxbridge Road which would create major congestion problems and divert a significant amount of traffic through residential areas.They also took the view that the reduction in traffic resulting from the tram would not be as high as that claimed by TfL, citing TfL's own impact studies of Croydon Tramlink.The Croydon system, the group noted, runs mostly on converted railway lines with only a short section of on-street track, and traffic displacement was managed by the construction of a new bypass; the West London Tram, by contrast, would run entirely along a highway which is hemmed in by narrow residential streets, with no scope for additional road construction.
