The proposal for rapid buses in Bristol is part of a bid to the DfT from all four LAs that used to be Avon County Council to access central govt.Transport Innovation Funding (TIF). One of the routes may use a small part of the cycle path, but until more details are available, I'm going to avoid condemning it.
There are many valid criticisms of the authority, but it should be remembered that they have been encouraged to develop schemes by central government in the past, only to be knocked back at the last minute.
I understand that details are likely to emerge in the summer, and will be subject to consultation.
