Vermont

'Vermont Route 12' begins at the New Hampshire state line in the town of Weathersfield. It continues north along the west bank of the Connecticut River, overlapped with U.S. Route 5, until Hartland. It then heads northwest to Woodstock and then north through Montpelier, Vermont to end at Vermont Route 100 in Morrisville. Vermont Route 12 runs parallel to Interstate 89 from the Woodstock/Hartford vicinity to Montpelier.

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.
Another alignment change occurred between Claremont, New Hampshire and Taftsville, Vermont in the late 1930s to early 1940s. The original route ran along the east bank of the Connecticut River in New Hampshire instead of along the west bank in Vermont. The original route used what is now New Hampshire Route 12A from Claremont to Lebanon, New Hampshire. It crossed the Connecticut River into White River Junction, Vermont along present-day U.S. Route 4, continuing west along U.S. Route 4 up to Taftsville, where it meets Vermont Route 12. From Taftsville to Montpelier, Vermont, the original route remains unchanged.
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.
