Bill, David, and I have all written posts about the upcoming reconstruction of Washington Avenue, primarily to comment on questions we have with the traffic analysis. In advance of the public open house meeting on Tuesday (at the Mill City Museum, you should attend), Hennepin County has posted four potential street layouts (thanks to @mplsbike for the tip).
Two include a cycletrack design, one includes on-street buffered bike lanes, and one includes no bike facilities with a “wide pedestrian zone”. All designs include 6 lanes of traffic. For reference, (at least for the cycling facilities) here is some NACTO guidance on one-way protected cycletrack design.
Update: the detailed birds-eye layouts of each concept can be found at the bottom of this page.
