CT 126 History
In the 1920s, State Highway 126 followed today's US 7 between US 1 and Route 35. Until about 1928, US 7 actually followed today's NY 22 outside Connecticut toward New York City.
The exact history of the modern Route 126 still needs some more excavation. 1930s state maps show a route from Route 43 (now Route 63) across US 7, through Falls Village, to end at the intersection of Sand Road and Belden Street. (Today's Point of Rocks Road was originally part of Sand Road.) In Falls Village, Route 126 followed Main Street instead of Brewster Road (its current alignment, one block north).
In 1936, it looks like Route 126 was shifted north to Brewster Road. The old Route 126 became SR 724.
In 1949, a state legislator submitted a bill to include all of Route 126 into the state highway system. Around this time, the signed route (if not the state maintained route) was extended to US 44 in North Canaan.
In 1951, for a short time, Route 63 was extended through Falls Village to US 44, taking over Route 126 entirely. The intent, announced to the public, was to create a continuous route from Woodbridge, near New Haven, to Canaan. However, the change was retracted the following year, restoring Route 126 and cutting Route 63 back to US 7.
In 1971, the town Planning Commission in Falls Village recommended moving Route 126 back to Main Street from Brewster Road. One reason cited was an unsafe intersection at Brewster Road and Point of Rocks Road, where Route 126 turns 90 degrees. The DOT replied that, if it approved the change, the town would need to eliminate angle parking on Main Street. Possibly for that reason, the change was never made.
