Source-derived summary

U.S. Route 9 (US 9) is a part of the United States Numbered Highway System that runs from Laurel, Delaware, to Champlain, New York. In New York, US 9 extends 324.72 miles (522.59 km) from the George Washington Bridge in Manhattan to an interchange with Interstate 87 (I-87) just south of the Canadian border in the town of Champlain. US 9 is the longest north–south U.S. Highway in New York. The portion of US 9 in New York accounts for more than half of the highway's total length.

The section of US 9 in New York passes through busy urban neighborhoods, suburban strips, and forested wilderness. It is known as Broadway in Upper Manhattan, the Bronx and much of Westchester County, and uses parts of the old Albany Post Road in the Hudson Valley, where it passes the historic homes of a U.S. President (Franklin D. Roosevelt) and Gilded Age heir. It passes through the downtown of Albany, the state capital, as well as Saratoga Springs. It penetrates into the deep recesses of the Adirondack Park and runs along the shore of Lake Champlain, where it is part of the All-American Road known as the Lakes to Locks Passage.

US 9 spawns more letter-suffixed state highways than any other route in New York, including the longest, 143-mile (230 km) New York State Route 9N (NY 9N). Outside of the cities it passes through, it is mostly a two-lane road, save for two freeway segments in the mid-Hudson region.

The current 248-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 1926. For this dossier, Route, York and United is the immediate research focus.
