New separate bit of bike infra here, replacing the lanes tagged on Marston Road: a 2-way, (itself) laned, non-foot cycleway separated from the motor carriageway with flexiposts. Can't remember what it does around the Crotch Crescent entrances, and we'll need to cycleway=link any interesting place where it joins to the legacy motor carriageway #SurveyMe

This one wiggles to the left onto the on-pavement track as it goes S, but merging onto the motor carriageway for a R turn onto Old Marston Road is possible thanks to the gap in the flexiposts.
