South of Cass Park, the about of the planned route follows the Cayuga Flood Control Channel along Route 13a, and then crosses the flood control channel (via a yet to be built bridge) directly opposite Cecil Malone Drive at Cherry Street, providing access to the Cherry Street Industrial Park, the city's Southwest district, and eventually to the new housing development planned there. From there, it follows the DL&W right of way built in 1849 as part of the Cayuga & Susquehanna railroad, crossing over the fish ladder and eventually goes underneath the Route 13 bridge near the Town/City of Ithaca line, and then proceeds parallel to its south side, terminating in Robert H. Treman State Park. This urban section of the trail is estimated to cost $5 million, mostly for the construction of three new bridges: the bridge connecting to Cecil Malone Drive, one near the fish ladder, and a third bridge crossing over the Cayuga Inlet near the trail branch connecting to Buttermilk Falls.
