Highway in 1973, an event which led to the demolition of the highway south of 59th Street. Demolition was completed in 1989. NY 9A was shifted onto 12th Avenue, one of the surface streets that the Elevated Highway had run atop of, but was otherwise unaffected as the route's south end was initially kept at the Lincoln Tunnel. In the mid-1990s, NY 9A was extended south to the Battery Tunnel by way of 12th Avenue and two other streets the Elevated Highway had previously run atop of, West Street and 11th Avenue. Construction began in early 1996 on a project to convert the section of NY 9A south of 59th Street into the West Side Highway, a six-lane urban boulevard with a parkway-style median and decorative lightposts. The first of the project's seven segments—between Clarkson and Horatio streets in the Greenwich Village neighborhood—was completed in 1998. Completion of the project was originally set for October 2001; however, it was delayed for years due to damage caused by the September 11 attacks. It was finished by 2014. Major intersections All exits on the Briarcliff–Peekskill Parkway and Croton Expressway are unnumbered.
