Route 15 in New York Designated I-99
July 09, 2014
N.Y. Gov. Andrew Cuomo announced the designation of Route 15 as Interstate 99 between Corning, Steuben County, and the Pennsylvania border.
The new expressway opened to traffic last fall following completion of $235 million in projects to construct the highway and bridges. The highway was built to federal interstate standards to allow this designation as Interstate 99.
This designation completes the final link in an 80-mile stretch of four-lane expressway between I-86 in Corning and I-180 in Williamsport, Pennsylvania. The newly designated Interstate 99 segment in New York and the adjoining four lane expressway in Pennsylvania allow for an uninterrupted high speed corridor between the two states, making shipping easier between Canada and points north with the southeast and mid-Atlantic states, according to the governor’s office.
