about from the split at a junction with NY 25 in Calverton. History Origins The route in Queens and Nassau County was originally an east–west Indian trail used to get from the current town of North Hempstead to Flushing. Meanwhile, the original road in Suffolk County was realigned and straightened in several locations prior to becoming a state highway. The old route is now known as North Country Road from Port Jefferson Station to Sound Beach (formerly CR 20) and from Shoreham to Wading River. From Smithtown to Saint James, it is now Edgewood Avenue (itself once CR 87). A handful of smaller, mostly local sections also exist. In Northport, the through road originally utilized Woodbine Avenue from Fort Salonga Road to Main Street and Bayview Avenue, and all of Main Street from there to Fort Salonga Road. In Setauket, it followed Main Street from Ridgeway Avenue and North Country Road to Old Town Road and current NY 25A. Finally, in Port Jefferson, the main road was initially East Broadway from Main Street and West Broadway to East Main Street, and East Main Street from there to the current Main Street. Designation All of modern NY 25A east of the New York City limits was originally designated as part of NY 25 in the mid-1920s. At the time, the section of Jericho Turnpike between New York City and Smithtown was state-maintained but unnumbered. It gained a designation when it was designated as NY 25A. By 1930, NY 25 was shifted southward onto its modern alignment between Smithtown and Riverhead while NY 25A was extended east over its former routing via Port Jefferson. In the 1930 renumbering of state highways in New York, the alignments of NY 25 and NY 25A west of Smithtown were flipped, placing NY 25 on Jericho Turnpike and NY 25A on the more northerly route via Roslyn and Huntington. NY 25A was one of several routes that was extended west into New York City in mid-December 1934 when the city signed routes within its limits for the first time. The route followed Northern Boulevard west across northern Queens to Queens Boulevard, which at the time carried NY 24 and NY 25. Here, NY 25A joined NY 24 and NY 25 across the Queensboro Bridge into Manhattan, where it followed 2nd Avenue and 57th Street for five blocks to meet NY 22 and NY 100 at Park
