Here are some photos of bicycle facilities in downtown Chicago from July 2014.
1. 2-way cycle track on Dearborn (looking south) at Madison, Chicago Loop
Dearborn is a 1-way street with 2-way cycle lanes. Note how narrow the lanes are. Does this meet design standards? There is also a falling hazard from the curb and a hazard from pedestrians stepping off the curb without looking because no moving cars are in that lane.
It would be best to eliminate the track entirely. This would give cyclists wider lanes. Blocks in downtown Chicago are short enough that it’s not a big time eater to have to detour one block west (to Clark St.) in order to go south.
2. 2-way cycle track on Dearborn, looking north, at Madison, Chicago Loop
Installation of the cycle track required prohibiting left turns on red from Dearborn onto one-way WB streets and from one-way EB streets onto Dearborn.
3. Hubbard looking east from Orleans, Chicago. Where’s the bike lane?
