CDOT is close to completing installation of the city's first protected bike lane--on Kinzie Street from Milwaukee Avenue to Wells Street.

The 1/2-mile lane is the first in Mayor Emanuel's plan for 100 miles of protected lanes citywide.

A protected bike lane provides bicyclists exclusive space in the roadway by separating bicycle and motor-vehicle traffic.  Installation began Monday, June 6 and will finish by month's end.

The protected lane sits adjacent to the curb.  Lane width varies between 5-1/2 to 7 feet wide.  The lane is separated from moving traffic by a 4-foot-wide buffer zone that includes flexible posts to help delineate the lane, as well as an 8-foot-wide parking lane.

Bike boxes

The new protected bike lane also includes a first-of-its kind element in Chicago:  Bike boxes.

Four of the boxes will be installed:  two at Milwaukee and Kinzie (for right and left turns from southbound Milwaukee), one at eastbound Kinzie at Wells,  and one at Kinzie and Desplaines.

A bike box sits at the front of a travel lane at an intersection, positioned in front of vehicles.  The bike boxes—which are 16 feet long and run the width of the lane—provide cyclists a place to wait at a red light where they are visible to motorists, and aren't exposed to vehicle exhaust.

The bike boxes will be painted with green, skid-resistant paint to help increase visibility.

Bike boxes have been used in many U.S. cities to increase safety, and have been effective in reducing so-called “right-hook” crashes, in which right-turning vehicles hit cyclists traveling straight through the intersection.

 

Kinzie bridge deck treatment

The open-grate deck of the Kinzie bridge is being modified with non-slip fiberglass panels to create a smoother riding surface.  The custom-fit panels will be fabricated by August, with installation following immediately.
