jurisdiction

Last month we noted that the Illinois Department of Transportation prevented the installation of a protected bike lane planned for Jackson Boulevard, allowing only a buffered bike lane on the segment of the street it controls. Now we know why: IDOT will not allow protected bike lanes to be installed on Chicago streets under its jurisdiction until mid-2014, at the earliest, because the agency wants to see three years of data (presumably crash data) before signing off on this type of street redesign.
