ok, I have removed the old incorrect crossing, and created a new one. I've left most of the tagging blank (I'm not sure if it's marked, for example), but I'll resurvey using StreetComplete.

Please be careful resolving notes of local mappers without visiting on the ground. I don't always have the detail as I know that I will resolve it later, and someone resolving it without that information from across the world leads to missing information.
