New York State Route 280 (NY 280) is an 11.59-mile (18.65 km) long north–south state highway in rural Cattaraugus County, New York, in the United States. The southern terminus of the route is at the Pennsylvania state line in South Valley, where it becomes Pennsylvania Route 346 (PA 346). The northern terminus is at exit 18 on the Southern Tier Expressway (Interstate 86 or I-86 and NY 17) in Coldspring, west of Salamanca. NY 280 follows both the eastern edge of the Allegheny Reservoir and the western boundary of Allegany State Park for its entire length.

When NY 280 was originally assigned as part of the 1930 renumbering of state highways in New York, it was little more than a short spur route off of NY 17 that followed the Allegheny River south to the hamlet of Quaker Bridge. In 1965, the Kinzua Dam was completed, leading to the creation of the Allegheny Reservoir and the inundation of much of NY 280. As a result, the route was shifted onto a new alignment that was constructed along the eastern edge of the reservoir.

Route description[edit]

Southern terminus of NY 280 at the Pennsylvania state line

At the Pennsylvania state line in South Valley, PA 346 exits the Allegheny National Forest and becomes NY 280 upon entering New York. The route heads north along the eastern edge of the Allegheny Reservoir as East Bank Perimeter Road, clipping the southwestern corner of Allegany State Park prior to entering the Allegany Indian Reservation. NY 280 passes in and out of the park once more before turning to the east toward Quaker Lake as it enters the town of Coldspring. At Quaker Lake, NY 280 penetrates the park boundary once more and intersects Allegany State Park Route 3 (ASP Route 3) at the Quaker Run entrance. Here, NY 280 turns north, traversing a small waterway separating Quaker Lake from the reservoir before reentering the Allegany Indian Reservation limits.[3]

NY 280 through Allegany State Park

Between ASP Route 3 and exit 18 of the Southern Tier Expressway (I-86 and NY 17), NY 280 continues to straddle both the eastern extent of the Allegheny Reservoir and the western perimeter of Allegany State Park before terminating at a diamond interchange with the Southern Tier Expressway. The West Bank Perimeter Road (unsigned NY 950A[4]), which parallels NY 280 from the Pennsylvania line northward on the western bank of the reservoir, meets the expressway at exit 17 2.5 miles (4.0 km) to the west.[3]


Original alignment of NY 280

NY 280 was assigned as part of the 1930 renumbering of state highways in New York to a short roadway connecting NY 17, then an at-grade highway, to the now-submerged hamlets of Cold Spring and Quaker Bridge along the western bank of the Allegheny River. The designation ended in Quaker Bridge, a community situated on the eastern riverbank near the modern junction of NY 280 and Allegany State Park Route 3 in the town of Elko.[1] NY 280 remained relatively unchanged up through the early 1960s.[5]

In October 1960, ground was broken on the Kinzua Dam, which would dam the Allegheny River downriver from NY 280 at a point east of Warren, Pennsylvania.[6] The structure was completed on December 13, 1965,[7] leading to the creation of the Allegheny Reservoir. Much of NY 280 was inundated by the new reservoir, as were Cold Spring, Quaker Bridge, and a significant portion of Pennsylvania Route 346 (PA 346) that ran along the river in Warren County. As a result, new alignments were built for both NY 280 and PA 346 along the eastern edge of the new reservoir.[5][8] Construction of NY 280's new alignment began in 1965 and was completed by 1968.[8][9] NY 280 now began at the realigned PA 346 at the state line and ended at exit 18 of the Southern Tier Expressway, which was built between Steamburg and Salamanca during the mid-1960s.[5][8]

Portions of the original Route 280 are still navigable during dry spells.[10]
