... the New York City Department of Transportation held its first Summer Streets event on Saturday by opening 7 miles of city streets to pedestrians and bike traffic only. From 7 AM to 1 PM, roads were car-free from 72nd Street to the Brooklyn Bridge with Park Avenue serving as the backbone of the route. ... The general consensus was that the event succeeded beyond even the most hoped for expectations and would pass even the most pessimistic of measuring sticks. ... the future will hold many more large scale street openings for pedestrians, cyclists, runners, children, dog walkers, dancers, and any other reasonable livable space use. ... Around noon, some blocks were getting very crowded, but there was a general courtesy that existed pedestrians and cyclists. The city built it - and the people came.
