I suspect that unless national government starts putting motorway-like sums into cycling infrastructure, most of it will continue to be funded by builders and this announcement does not appear to require councils to spend builders' funding only on standards-compliant stuff. What we really need is full compliance with LTN 1/20 adding to the binding planning policies, so councils must neither approve planning applications or discharge planning conditions if the cycleways are crap. .
And that, in my view, should now be the first priority for campaigners and lobbyists. Planning regulation is getting a fundamental review also, so this is the best opportunity for a long time. It's also a matter of DfT/DCLG communication: and on that score the Cummings-led push to centralise control of the different govt. departments could be helpful.
