Don’t be fooled by the bike lane map that WGN TV displayed yesterday morning on television. There’s a stark difference between the lines on that map, which denotes the location of all bikeway types (a part of transportation infrastructure, with pavement markings) and recommended bike routes (not a part of transportation infrastructure, without pavement markings), and the lines you see on the ground (a large portion of which are faded). A superimposed “bike lane” sign and the single color representing the aggregated bike lanes, marked shared lanes, and recommended routes, make it seem as if there are more bike lanes than actually exist.
Chicago doesn’t provide an up-to-date online map, but occasionally updates the bikeways geodata on its open data portal (which I used to create the right side map of the above image). The City is short 20 miles of protected bike lanes for the first year of four (25 miles per year, 100 miles total), which ended May 16, 2012.
