I've visited Riverside to Waterbeach with William Rayner of county cycling team. He's revising signage here and providing it along the St Ives corridor, with the old NCN 51 being renamed Regional Route 24 (blue patch). We've decided finally to continue to sign NCN 11 from Riverside Bridge to Waterbeach Station, and he's looking at suitable (hopefully temporary) wording to advise to follow NCN 51 to Bottisham for destinations beyond Waterbeach, which will hopefully eliminate misrouting those from outside the area.
Our inspection of existing signs showed that only one new signboard was provided on completion 5 years ago of Riverside Bridge. Signboards still send people via Green Dragon. Sustrans considers signage is an important part of any route project.
The intention is to sign Milton Country Park as a destination, not as part of the route, removing route signs within the park, and probably retaining Coles Road as the signed route through the village, though it would be much preferable to have improvements past the shops and the village green, pubs etc.
Retaining the route to Waterbeach as NCN will help keep the gap in people's awareness.
I am planning to contact again the landowner of the missing link between Bottisham Lock and Fen Road, Lode with a suggestion for a low-level route, southeast side of the Bottisham Lode floodbank which is the route of the public footpath, where signs forbid cycling. It might be considered more visually acceptable. All parish councils are for the route, including the one of which he is a member.
