List of Numbered Highways in New York - Thruway

Thruway

Highways maintained by the New York State Thruway Authority lack any signed numbers apart from Interstate Highway designations. While the vast majority of the Thruway system is part of the Interstate Highway System, some sections, such as the Berkshire Connector between Interstate 87 and Interstate 90, are unsigned reference routes. There are no standard NYSDOT reference markers on any of the highways; instead, the Thruway Authority posts their own mileposts, which (aside from the mainline) bear special Thruway codes. See the Thruway article for details.
