D.C. Bike Lane Expansion Helped By Warm Winter

WASHINGTON -- Warm weather conditions this winter may have contributed to the early bloom of the cherry blossoms. But it also helped something else blossom: the number of miles of bike lanes in the nation's capital.

According to the D.C. Department of Transportation, the agency has installed four new miles of bike lanes and one mile of shared lanes around town since Jan. 1.

Where are the new lanes? On 4th Street SW, I Street SW, I Street SE, Columbia Road NW, New York Avenue NW, Tilden Street NW and Upshur Street NW.

Additionally, new sharrows and shared bike lanes have been installed on Oklahoma Avenue NE and R Street between Florida Avenue and the Metropolitan Branch bike trail.

This summer, transportation officials plan to construct a cycle track on L Street NW between New Hampshire Avenue and 12th Street NW, helping to create an east-west crosstown spine for bicycles to complement the heavily utilized north-south 15th Street NW cycle track.
