Its a Way under a building where the building is either on legs or exists
above and on both sides on the way. The way not blocked by a door (to enter
the building). However other barrier (eg Staggered Fence or Gate) may exist
to limit access to the way. The way is however at ground level.

That way maybe or any type including road, railway or waterway....

These are quite common in the Uk. (Do I need to find a photo)
