Shouldn't this way (highway=footway) be more appropriately tagged?

The way is part of a LCN-bicycle-route, relation 3322620, therefore some tagging allowing cycling seems required.

I stumbled over this, browsing the opencyclemap for edit-hints on relations in general (no survey).

Incidentally, the route does not appear very "route-like" as the ones I'm familiar with so far. Apparently it merely reflects plain bicycle markings, but maybe it serves a purpose (in GB).

This Lambeth label should actually be in the vicinity of Lambeth Walk (site of the former Lambeth High Street) and the part of the borough that actually takes the name.

Where it is here is, to all intents and purposes, Waterloo.
