Interstate 88 (Eastern)

Overview

An intrastate route in Upstate New York, Interstate 88 angles northeast from Binghamton to the Capital District along a scenic and rural route. Smaller cities and towns along the route include Sidney, Oneonta and Cobleskill. East from Harpursville, I-88 travels along side the Susquehanna River through a valley to the Town of Milford by South Hill.

Underway from October 2026 to the end of 2026, a $1.1 million project converts the sequential exit numbering system along Interstate 88 to a mile-based system. Sign changes started at Port Crane, where Exit 3 was renumbered to Exit 4. Work moves east to I-90 (New York State Thruway), where Exit 25 becomes Exit 117 (Rizzo, 2026).

History

Not incorporated in the original 1956 Interstate Highway plans, the eastern Interstate 88 was established in 1967 (The Times Union, 1986). The New York Legislature authorized the highway in 1968, with major construction underway between 1974 and 1980 at a cost of $500 million (The Times Union, 1989a). The freeway replaced New York Route 7 between the Southern Tier and Schenectady.

The last portion built was the 1.5 mile segment between Interstate 81 and Chenango Bridge. Included on this section is the 2,650 foot long bridge across the Chenango River. Work on the $20.3 million link ran from 1987 to January 1, 1989 (The Times Union, 1986). The freeway was named the Warren M. Anderson Expressway in 1989, after the former state Senate majority leader and proponent of the I-88 corridor (The Times Union, 1989b).

An eastern extension between Schenectady to Albany was approved by the American Association of State Highway Officials (AASHO) on June 23, 1969, but never signed. A second plan to lengthen I-88 arose in 1999 when the Thruway Authority, New York State Department of Transportation (NYSDOT) and the Federal Highway Administration (FHWA) proposed renumbering the free portion of I-90 between the Thruway Mainline and the Berkshire Spur as I-88 while shifting Interstate 90 entirely on the toll road system. This was also never implemented (Getting There, 2010).

Interstate 88 was fully open from NY 7 north of Port Dickinson to Oneonta in 1979. The portion east from Oneonta to U.S. 20 near Duanesburg was completed the following year.
