The main road connecting the towns of Cornwall and
Canaan was designated as a state highway in 1922, and was known as Highway 132. The road began in Cornwall center, passed through the villages of Cornwall Hollow, Lower City, and Huntsville, and ended in
Falls Village in Canaan, following modern Route 43 then modern
Route 63 and modern
Route 126. In the
1932 state highway renumbering, old Highway 132 was renumbered to Route 43 except for the northern end. Route 43 ended at
U.S. Route 7 in the village of South Canaan, instead of Falls Village. The road to Falls Village became Route 126. On September 11, 1951, Route 63 was extended into the town of Canaan using the northern portion of Route 43. This resulted in Route 43 being cut back to its current northern terminus. ==Junction list==
