OpenStreetMap
I started editing Duke Street in Alexandria, Virginia, USA at the location selected for this diary entry. I'm, basically, just making it a divided roadway, but please let me know if I'm taking my edits in the wrong direction.
Some specific things I'm not sure about are:
- Should I copy the tiger data from the original Duke Street into the new way that I'm creating?
- Should tiger name data be corrected in the existing tiger tags or should I create new tags?
- How do you connect the ways on a divided road if there isn't a road that crosses them? (i.e. if theres a break in the median, how is that labeled if it's not associated with another roadway?)
- Should rivers and streams be labeled as lower layers than roadways, or should roadways be labeled as higher layers than rivers and streams?
- If I'm labeling a ramp as a higher layer than a roadway that it crosses should I label the entire ramp even though most of the ramp is at the normal road level, or just the section that is actually above the road similar to how bridges and tunnels are labeled?
Happy mapping!

I'm not sure there is THE way to do things, but on your question about how to tag roads crossing waterways here is what I do: If there is an actual bridge I tag the bridge at layer 1 and leave the waterway at its default layer 0; if a stream is just passing under the road in a pipe or something similar, I tag the stream section passing under the road as layer "-1" and leave the road at default layer 0

I guess all that really matter is that it is rendered correctly. I think I'll start doing it your way. Right now, the road and stream in the section I was working on are at the same layer, so it would rely on some sort of default behavior in the renderer to get it to look right. Thanks for the help.
