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.
