I apologize for not getting some of the parts right. Just wanted to clarify that I am not a paid mapper as you suggest but someone using OSM for the first time. I am trying to help with a project and I am sorry I got some stuff wrong. The only tags I changed were when OSM was telling me there were messing tags and I only added what it suggested when it made sense to do so. As for splitting crossings, I will be more careful but I had no intention of messing anything up. Just wanted you to know i’m a college student trying to help with a project using a website for the first time instead of an organized and paid mapper as you suggested so I will try but it probably won’t be perfect.
