CT 137 History
In the 1920s, State Highway 137 followed today's Route 101 between modern-day Route 169 and Route 12.
Commissioned in 1932, the modern Route 137 formerly entered Stamford center via Summer St. south of Route 104, but as of 1976 takes Washington Blvd.
In 1959, the state allocated $2.2 million to widen High Ridge Road (Route 137 between Route 104 and the Merritt Parkway) from two lanes to four lanes.
On June 28, 1962, a four-mile section from Long Ridge Road to the Merritt Parkway was dedicated the Yankee Division Highway, honoring New England's 26th Division which served in World Wars I and II.
Tentative freeway proposal, 1960s
There were a few area proposals for a north-south highway between Stamford and Pound Ridge, N. Y. or Bedford, N. Y. In 1956, the Westchester Planning Department proposed a high-speed "Stamford - Bedford Village Road" between Routes 104 and 137, though noting that the route "might be cancelled."
In 1962, the Tri-State Transportation Committee proposed an arterial upgrade: four lanes divided with a median, no access control, from I-95 to the Merritt Parkway. This did get implemented along the Washington Boulevard segment in 1976.
In 1969, Westchester county proposed upgrading Route 137 to a freeway, from NY 172 south. Route 137 would have had interchanges at Route 15, Route 104, US 1, and I-95. This plan was not adopted and is now inactive.
