A section of the Cotswold Way National Trail on Leckhampton Hill was recently improved to make it suitable for off-road Tramper wheelchairs and mobility scooters.
The path has been widened and resurfaced:
Steps where the path meets Hartley Lane have been replaced with a ramp:
I’m not sure how best to tag this. Using wheelchair=yes doesn’t seem correct as a more rugged chair or mobility scooter is required. Looking at Taginfo for wheelchair I don’t see “off-road” or similar. The Key:wheelchair wiki page doesn’t help either.
Even the experts on the #osm-gb IRC channel seemed unsure how to tag this, but pointed out that such paths are becoming more common (see Rambles on wheels), so I thought I’d ask the wider community.
Better accessibility tagging is also useful for people who don’t use wheelchairs, but have restricted mobility. Someone at the volunteer group which helps look after the hill told me that the ramp has opened up the hill to people who have been unable to walk there for years.
