I just completed laying out the highway and entering basic tagging for all of I 81, including the intersections, in Maryland. I'll need to go back and correct some of the streets that cross it, and enter exit numbers, but other than that, I think all the basic info is there.

I'll also need to go back and create/add relations for the Maryland section of I 81 as the reply to my previous diary entry describes. If anyone wants to critique what I've done, I would appreciate it. The highway is the North-South road in this general location:

Please let me know if I've been leaving out any major/common tags, and what kinds of details should be included on US Interstate Highways - probably number of lanes, speed, etc. I've read about lots of things that can be added, but the Wiki and talk pages didn't really make it clear if there was some sort of standard people were following.

I moved to Maugansville, Maryland recently. So I probably won't do quite as much editing around the Alexandria, Virginia area. I've started lining up roads with the images for my new neighborhood, and I've started working on the nearby highway. If anyone can explain what I should do about relations for the highway, I could use a step-by-step guide.

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!
