project forced a portion of the route to be rerouted northeast of Horseheads. Due to the elevated water level caused by the dam, the route had to be moved to higher ground west of the hamlet of Sullivanville in the Town of Veteran. A section of the old highway remains under the impounded water. Another section north of the dam exists as an extension of Sullivanville Road. In 2007, with the completion of the I-86 project, NY 13 was extended westward along the parallel collector/distributor roads to NY 14 in Horseheads. Prior to the project's completion, at least one "NY 13 south" sign assembly was exposed along the westbound frontage road leading from exit 54 (NY 13). Several similarly shaped signs on similar sign assemblies were covered along the route. Routing through Ithaca When NY 13 was first assigned, it entered the city of Ithaca on Spencer Road and followed Spencer and Cayuga Streets into downtown. From there, NY 13 proceeded generally northeastward on Court and Linn Streets, University Avenue, and Forest Home Drive through the Cornell University campus to Dryden Road, where it turned eastward toward Dryden. NY 13 was realigned to bypass the Cornell University grounds to the south on State (NY 79) and Mitchell Streets and Ithaca and Dryden Roads. Its old alignment through the college became NY 392. In the early 1960s, a new expressway was built along the eastern shore of Cayuga Lake, bypassing downtown Ithaca on the west and north. NY 13 was altered to follow Meadow Street and the freeway between southwestern Ithaca and the town of Dryden while the portion of NY 13's old routing that did not overlap NY 79 became an extension of NY 366. The freeway was expected to be continued all the way to Cortland, but was abandoned with the completion of the existing segment of the highway; the remaining connection to the old NY 13 was completed as a two-lane roadway. The new expressway was pictured on the Voyager Golden Record as an example of a "modern highway." In 1996, ten blocks of southbound NY 13 was diverted from Meadow Street to Fulton Street as part of the Octopus elimination project. Major intersections NY 13A NY 13A is a north–south spur that bypasses downtown Ithaca by way of the town of Ithaca to the southwest. The route begins at NY 13, NY 34 and NY 96 south
