The original brick and stone shelter leading to the entrance of the 72nd Street subway station, one of the first 28 subway stations in Manhattan, remains located on one of the wide islands in the center of Broadway, on the south side of West 72nd Street. For many years, all traffic on Broadway flowed on either side of this median and its subway entrance, and its uptown lanes went past it along the western edge of triangular Verdi Square. In 2001 and 2002, renovation of the historic 72nd Street station and the addition of a second subway control house and passenger shelter on an adjacent center median just north of 72nd Street, across from the original building, resulted in the creation of a public plaza with stone pavers and extensive seating, connecting the newer building with Verdi Square, and making it necessary to divert northbound traffic to Amsterdam Avenue for one block. While Broadway's southbound lanes at this intersection were unaffected by the new construction, its northbound lanes are no longer contiguous at this intersection. Drivers can either continue along Amsterdam Avenue to head uptown or turn left on West 73rd Street to resume traveling on Broadway.
