As I suspected, construction began today, Monday, June 6, 2011, on Chicago’s first 0.5 miles of protected bike lanes at Kinzie and Desplaines.

Chicago Department of Transportation employees were out on the street this morning striping the bike lane and bike lane buffer, as well as a painted “median” at the start of the bike lane that will presumably keep out automobiles.

Looking east on Kinzie from Desplaines, down hill. More photos.

Looking west on Kinzie from Jefferson, up hill. More photos.

The configuration is probably a 5-feet bike lane, 3-feet buffer zone (which will soon have soft-hit bollards), 8-feet car parking lane, and 10-feet travel lane. As of 9:30 AM this morning, when the photos were taken, crews had not worked on westbound Kinzie Street.
