CHICAGO (CBS) — Mayor Rahm Emanuel has announced Chicago is building 33 miles of new bicycle lanes this year.

As WBBM Newsradio’s Dave Marsett reports, the protected bike lanes are part of a planned nearly 650-mile network of biking facilities to be in place by 2020. The paths include a protected path on Dearborn Street that will feature traffic signals especially for cyclists.

The city says the bike lane project will provide a bicycle accommodation within half-mile of every Chicagoan, and will be instrumental in creating the quality of life Chicagoans are seeking.

Last year, the city installed and re-striped 39 miles’ worth of bike lanes. Last year also marked the opening of the first protected bike lane, along Kinzie Street between Milwaukee Avenue and Wells Street.
