Main braided street list doneI have finished correcting the "braided" streets listed on the Tiger fixup page.
I've been looking for more to fix, and I haven't found many. I found a handful more in the greater Bay Area, mosly in Oakland. None in Portland. A few duplicated streets in Tacoma, but no actual braided ones anywhere around Tacoma and Seattle.
I'm going to broaden my search across the US, but I'm wondering if the underlying issue was peculiar to the San Francisco area. Since the TIGER data is an amalgam of other sources, it could be that the topology leading to the braiding phenomenon only occurred in some source data from that area. Interesting.
