New England Route 12 was a multi-state north–south state highway in the New England region of the United States, running from Groton, Connecticut, through Worcester, Massachusetts, and Keene, New Hampshire, to Morrisville, Vermont. Its number dates from 1922, when it was a New England Interstate Route, also known as the Keene Way. A multi-state "Route 12" still exists, bearing the names of the states through which it passes, and partially following the original alignment of the New England Route.
History
The southern terminus of Route 12 was originally at New London, Connecticut. It travelled along present-day Route 32 (along the west bank of the Thames River) from New London to Norwich, Connecticut. In 1932, when Connecticut decommissioned its New England Routes, Route 12 swapped places with Route 32 south of Norwich. From Norwich, Connecticut to Claremont, New Hampshire, Route 12 still follows its 1920s alignment.
The original northern terminus was at Derby, Vermont. In the 1960s, the route was truncated and the northern terminus was moved to its present location at Morrisville, Vermont. The original route ran along what is now Vermont Route 14 from Montpelier to Hardwick, Vermont Route 16 from Hardwick to Barton, and U.S. Route 5 from Barton to Derby.
