In the coming weeks, CDOT will install its first green bicycle lane markings on E. 4th Street near College Street. This new traffic control device is designed to enhance awareness of the bicycle lane at the right turn lane from E. 4th Street to College Street.
Green bicycle lane markings are emerging as a new tool that can be used for bicycle safety on roadways. These devices have been successively used by many municipalities such as New York City, San Francisco, St. Petersburg and Minneapolis. The Federal Highway Administration (FHWA) has granted interim approval for use of green bicycle lane markings on city maintained streets.
CDOT has additional potential locations to install green bicycle lane markings. These are on Kenilworth Avenue at Charlottetowne Avenue and E. Stonewall Street from Charlottetowne Avenue to S. McDowell Street, as well as on E. 10th Street at E. 12th Street. CDOT will observe the sites before and after installation of the green markings to evaluate driver and bicyclist behavior.
The E. 4th Street location was chosen due to heavy bus and vehicle utilization of the right turn lane onto College Street and known existing bicycle traffic. The Kenilworth Avenue and E. Stonewall Street locations were chosen because of the frequency of right turn lanes to Charlottetowne Avenue, the I-277 ramps, and McDowell Street, as well as known existing bicycle traffic. The 10th Street location is a citizen-requested location where vehicles frequently encroach into the bicycle lane to make the right turn movement.
