History
Route 12 was preceded by New England Interstate Route 12. The southern terminus of NE-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 to the Massachusetts border, Route 12 still follows its 1920s alignment.
