	The highway from 59th to 72nd Streets is the only elevated section that remains today, although it conflicts with plans for the Riverside South development project and neighborhood. A covered, at-grade replacement road to facilitate a southward expansion of Riverside Park was approved by the Federal Highway Administration in 2001. In June 2006, the developer began construction of a tunnel between 61st and 65th streets for the relocated highway. However, the rest of the tunnel remains unfinished.
