Thanks to Chris for the tip via Twitter – most of the “rechannelization” striping is in on the north end of Delridge Way SW, basically between the south side of Youngstown Cultural Arts Center and the West Seattle Bridge.

As you might notice in the video, some painting remains to be done – bike lane and bus lane stenciling, for example. Here’s the county’s explanation of what was changed (see the link in that page’s sidebar).
