It's really happening: Workers are getting ready to transform Broadway traffic lanes into a pedestrian oasis as part of the DOT's plan to ban cars from part of the city's main stem. Mayor Bloomberg and other officials announced the radical move back in February; it involves rerouting vehicular traffic from part of Broadway to Seventh Avenue, a move that they say will improve traffic flow because Broadway itself creates congestion as it cuts southeast across the avenues. Pedestrian plazas with tables and chairs, similar to the new "Broadway Boulevard," will entirely replace motor vehicles on Broadway between 42nd and 47th streets and from 32nd to 35th streets. According to 1010 WINS, work will begin Memorial day weekend, and the transformation will include bike lanes in both sections. According to the DOT, the changes, which include widening Seventh Avenue with another traffic lane, are an "experiment" that will last through the end of the year but may become permanent.
