	By 1989, the old elevated highway structure was totally dismantled except for a small portion from 59th Street to 72nd Street, which, in effect, became the southern extension of the Henry Hudson Parkway. Eventually, a grade-level six lane "urban boulevard" was built, which is generally referred to as the West Side Highway, although the elements of it use the names of the surface streets which existed before the elevated highway was built: West Street, Eleventh Avenue and Twelfth Avenue. It connects to the remaining elevated structure via a ramp at 57th Street.
