The state has a new interstate highway.

The new Route 15 expressway between Corning and the Pennsylvania state line is now Interstate 99.

The formal designation completes the final link in an 80-mile stretch of expressway between I-86 in Corning and I-180 in Williamsport, Pennsylvania.

Governor Cuomo says the expressway is making shipping and travel throughout the northeast easier and more efficient. And he says that’s good for commerce and tourism.
