My sat nav thinks this road (east of Vickers Bridge) is open to the public at all times without charge. The presence of a gate suggests otherwise. Can someone confirm, and/or adjust the access permissions on the roads either side of the gate, please?

Shouldn't the dark main road colour extend down to the M3 for the A339 as it is a trunk road throughout to said M3.

way/3109897 appears to have incorrect access: access=designated implies all have access; motor_vehicle=designated (normally used on Byways Open to All Traffic where motor vehicles are allowed and sometimes on motorways) implies this is a right of way for motor_vehicles, but this is highway=pedestrian. Should "designated" be replaced by either "private" or "destination"?

The road and cycleway layout does not make sense. Should the new roads (with "Dualling Project" in the name) and the new cycleways (the ones with no details about width, surface, segregated, lit) be marked as highway=construction and the old ones retained, or should the old ways be deleted and the new ways have data about surface/lit/segregated added as appropriate?

tagging on way/663114608 does not make sense. If this is proposed, then should be set to highway=proposed and proposed=cycleway. Details on proposed values of lit, segregated, surface, foot (i.e. whether pedestrians are allowed also), and width would be appreciated if available.
