Post Road). This intersection serves as the northern terminus of NY 137. History The roadway that make up NY 137 from NY 121 in the town of Bedford to Westchester Avenue in the area of Horseshoe Hill along with the alignment of former NY 137A was upgraded to state standards in the early 1900s. The segment, designated as unsigned State Highway 1306 (SH 1306), , was given a contract on August 31, 1915. The highway took over six years to complete, with construction being completed on November 23, 1921, at the cost of $111,453.53 (1921 USD) with $72,446.09 paid by the state of New York. NY 137 was first designated in the 1930 renumbering of state highways in New York as a continuation of the road leading north from Stamford, Connecticut. The original route ran from NY 22 north of the hamlet of Bedford to the Connecticut line by way of Girdle Ridge and Pea Pond roads and a short overlap with NY 121. On September 1, 1980, ownership and maintenance of Girdle Ridge and Pea Pond roads was transferred from the state of New York to Westchester County as part of a highway maintenance swap between the two levels of government. NY 137 was truncated to the southern terminus of its overlap with NY 121 as a result. The former routing of NY 137 along Girdle Ridge and Pea Pond roads was redesignated as County Route 309. An expressway was planned along the NY–CT Route 137 corridor in the 1950s. NY 137A NY 137A was a spur route in the town of Pound Ridge that connected NY 137 to the Connecticut state line, where it connected to State Highway 184 (later Route 124), by way of Westchester Avenue. It was assigned as part of the 1930 renumbering of state highways in New York. NY 137A was renumbered to NY 104 , which in turn was renumbered to NY 394 to eliminate numerical duplication with U.S. Route 104 in Upstate New York. In 1967, NY 394 became an extension of NY 124. The extension was short-lived as NY 124 was truncated back to the hamlet of Pound Ridge by 1970. Westchester Avenue is now maintained by the town of Pound Ridge.
