St. Mark's Road to Holloway cut-through
This shortcut is technically pedestrians-only, but forms a useful link from the environs of Bath Spa station (Widcombe) to Holloway, a dead-end for motor vehicles and therefore a quiet, if steep, climb to Bear Flat, Wellsway and beyond.
Dropped kerbs, barrier/chicane removal etc. would make this route usable by parents with cycle trailers, people on cargobikes and the like.
It was slated as a piece of work to be done by Bath & NE Somerset, but there's been no news lately.
