Who's "we"? And it's sick that landowners are allowed to block cycleways, but if it was a motorway and only one or two landowners, it'd be compulsory purchased in a heartbeat.
I know it's scandalous. I've long thought that if we were really serious about sustainable transport in the UK (which of course we're not) , some kind of compulsory purchase should be available for such critical routes (this one would not only provide a key off road route into Cambridge but would also allow them of us what live to the east of the Cam, easy access to our closest as the crow flies, railway station at Waterbeach).
I better not say in public who the 'we' are as it's a rather sensitive issue, but it's a loose collective of Lodes Way users, combined with shall we say by key local partners.
Apologies for slightly derailing the thread and hope the cyclist in the OP is OK
