I'm trying to make my mind up over this.
Back in 2014 it was definitively a carriageway, complete with DYLs and give way markings.
These disappeared when new tarmac was laid.
And the building development has since been completed.
It now seems like a vehicle crossover, which is not part of the carriageway.
However, I suspect that this a CPZ and fails in that "all parts shall be marked with yellow lines or parking bays"
Not in the sense that Herron tried to claim in Sunderland but immediately, this is a patch of highway where its purpose is not obvious.
Further opportunity to mislead with the no entry sign, which would normally, though not always, be on a carriageway.
The buy a plan picture...where does this come from?
