Correct description: "Finished adding a fence originally added in changeset/140775207, added two trees and a streetlamp to add as references to correctly depict the geometry of the adjacent cycleway. Updated tagging of cycleway."

Looks good!

It's pretty close. Add an area for the median with the tag area:highway=traffic_island. If you wanted to match the wiki exactly, make the ways between the median's curb and the sidewalk's curb footway=crossing, but personally, I don't know how necessary that is since you've already got a node as a crossing; I see many more nodes as crossings than ways.

I updated this crossing to match this example. If that's fine with y'all, you or I can make a similar update at 45th & Lyndale.

Hi jumbanho, it's cool to find someone interested in the same things I am! Just so we're on the same page, you're talking about how I split footpaths out from the cycleway, like how way#911885632 diverges from way#911885631 near the intersection of 38th Ave S and West River Parkway?

If you are, I began splitting out footpaths approximately where the paths diverge in reality. Where the footpath is directly attached to the cycleway, separated only by paint, I tried to preserve a single way with highway=cycleway+bicycle=designated+foot=designated+segregated=yes; and where the footpath diverges, separated from the cycleway by soil, I tagged the footpath as highway=footway+bicycle=no and the cycleway as highway=cycleway+foot=no. Not only are the paths literally separated, that's also what the path markings specify.

In this specific example, the segregated=yes tag is unnecessary on the cycleway north of this intersection, and I see how that may be confusing. I'll need to remove it from the paths I edited.
