It looks like the City’s promise to build out the bike network is already bearing fruit. Streetsblog reader Alex Kahl sends along these photos of new bike lane markings being striped on W. 77th and W. 78th Street near Columbus Avenue. Unlike the new, Class III, "shared lane" markings spotted yesterday in the middle of Clinton Street near Delancey, it looks like these are going to be Class II lanes running along the side of the street.
