the segment from 43rd to 59th streets was left standing, since it was thought that it could be refurbished and integrated into an extension of westway. the remaining highway would be funded separately, as interstate funds could not be used to connect an interstate highway to a limited-use facility (in this case, the henry hudson parkway). ramp and lane improvements were made in 1981, permanently closing the highway south of 59th street. previously, northbound traffic could enter the highway at 43rd street and southbound traffic was directed off the highway at 59th street. the city demolished the 43rd-59th street portion by october 1989.
