New York State Route 454 (NY 454), also known as the Suffolk County Veterans Memorial Highway or simply Vets Highway, is a 13.67-mile (22.00 km) east–west state highway in western and central Suffolk County on Long Island in New York. It spans from NY 25 (Jericho Turnpike) in Commack to NY 27 (Sunrise Highway) in Holbrook. The route provides access to the Long Island MacArthur Airport, as well as New York State and Suffolk County government offices, and at one time the Long Island Arena. NY 454 serves as the northern terminus for the Northern State Parkway in Hauppauge, where a concurrency with NY 347 begins.
The origins of NY 454 dates back to the late 1940s when a new freeway was constructed from Commack to Holbrook for $1.4 million ($17.9 million in 2023). This new freeway was designated as a memorial for Suffolk County War Veterans. The route was designed and constructed by the Suffolk County Department of Public Works under watch and aid from the New York State Department of Public Works and the United States government. Upon completion in January 1950, the route was designated as County Route 76 (CR 76) west of Town Line Road and CR 78 southeast of Town Line Road until 1968 when the entire highway was designated CR 78. In 1972, the state took over control of the new highway and designated it NY 454. Recently, there have been plans to expand the highway and the concurrency with Route 347 with new travel lanes and a new interchange being built between the two highways.
