route meets with the concurrent routes of NY 34 and NY 96 at an interchange adjacent to Robert H. Treman State Park, becoming Elmira Road. Both routes join NY 13 north alongside the eastern edge of the park to NY 327, a road largely delimiting the northern extent of the park. The three routes proceed generally northeastward through the town of Ithaca to the vicinity of Buttermilk Falls State Park, where they intersect the south end of NY 13A, an alternate route of NY 13 through western Ithaca, near the former Tutelo village of Coreogonel at the confluence of Buttermilk Creek and the Cayuga Lake inlet. NY 13, NY 34, and NY 96 continue on, directly serving Buttermilk Falls State Park as they pass over the creek and inlet and enter the Ithaca city limits. At West Clinton Street (NY 96B), the route splits into a one-way pair, with Meadow Street carrying northbound traffic and Fulton Street handling southbound traffic. Due to the configuration of the city street grid, NY 79 overlaps the three-route concurrency on Fulton Street for one block eastbound as it switches from West State Street to West Green Street; no such overlap exists westbound/northbound as NY 79 westbound remains on West Seneca Street, where NY 96 leaves NY 13/34 and joins NY 79. The one-way pair comes to an end near Hancock Street, at which point both directions of the route merge into Meadow Street and continue northeastward through the city as an at-grade roadway. At Dey Street, however, the road becomes a limited-access highway as it heads through the northern extents of the city and partially alongside Cayuga Lake. Near the northern city line, the roadway connects to East Shore Drive by way of an interchange, at which point NY 34 leaves the expressway to follow East Shore Drive along the lakeshore. NY 13 and NY 34 follow parallel routings into Lansing, where NY 13 curves eastward to interchange with both Cayuga Heights Road and Triphammer Road. Southwest of Ithaca Tompkins International Airport, NY 13 downgrades into a divided highway and meets Warren Road at-grade before reverting into a two-lane roadway as it passes south of the airport and exits the Ithaca area. Ithaca to Lenox NY 13 progresses southeast through western Dryden to meet Dryden Road (NY 366), a street originating in eastern Ithaca. NY 366 joins NY 13 northeast along Fall Creek for
