convert the entirety of NY 17 to an Interstate and stated that the conversion would be fully completed by 2009. However, a severe lack of funding has pushed the completion date back. , the only portion west of Binghamton not officially designated as I-86 is between the Chemung–Tioga county line and the junction with I-81. The designation on this segment cannot be applied before NYSDOT completes the Prospect Mountain construction project at the junction of I-81, US 11, NY 17, and NY 7 in Binghamton, which when complete will bring the roadway up to Interstate Highway standards. The official completion of the project was set for December 2020. Work on converting the portion of the highway east of Windsor is expected to be far more substantial than the work west of Binghamton. Currently, the only portions up to Interstate standards east of Windsor are between exit 94 (Roscoe) and exit 100 (NY 52), between exits 104 and 106 in Monticello, and between exit 116 (NY 17K) and exits 121–122 (I-84/Crystal Run Road). Aside from numerous minor interchange improvements, major work includes constructing two new interchanges in the mountainous Hale Eddy area, exits 85 and 86, to replace two at-grade intersections, as well as the relocation of driveways in that area, improving curve radiuses throughout the route, and widening the shoulders on narrow parts of the highway. Work was completed in November 2019 on a redesigned interchange at exit 131, where NY 17 meets I-87 and NY 32. Work is also underway to bring exits 124 and 125 in Goshen up to Interstate standards, which is expected to be completed in early 2020. There is no timetable for the full completion of the I-86 conversion between NY 79 in Windsor and the thruway (I-87) in Harriman. Nevertheless, segment between Bloomingburg and Goshen is signed as I-86 and NY 17. In October 2022, Governor Kathy Hochul announced that a draft environmental impact statement on upgrading Route 17 to transform it into Interstate 86 was underway, public outreach was expected early in 2023, and that up to $1 billion was available for the work. Exit list Pennsylvania uses milepost-based exit numbers on its Interstate Highways; other I-86 exits are numbered sequentially.
