Exit from Heartsease roundabout onto Plumstead Rd. There is a shared footway on the left next to the zebra part of a parallel crossing. After the crossing there is a cycle symbol & give way sign with "Cyclists rejoin carriageway" sign

Aerial view of Tuckton Roundabout showing parallel crossings on all arms but with shared footways all round

Sadly shared use footways, "Cyclists Dismount" signs & some poor transitions (photo) probably disqualify it. In my view #ParallelCrossings alone aren't enough, otherwise #Tuckton RB #Christchurch (or #Bournemouth? @engineerlikeagirl.bsky.social) would be first UK DSR maps.app.goo.gl/yKUs27K8qSHp...
