119 is the only signed route number in Connecticut that has been used, and abandoned, three times.

SH 119, Danbury

From 1923 to about 1928, when US 6 was commissioned and displaced it, State Highway 119 followed today's US 6/202 from Danbury to the New York state line.

Waterbury to Bristol

From 1932 to 1934, the next Route 119 followed today's Route 69 between Waterbury and Bristol.

Groton to North Stonington

From 1935 to 1963, Route 119 was a short highway in Stonington and North Stonington. It took over SR 668, an unsigned route on Mystic Road leading from the Stonington town line to Route 2 in North Stonington. The North Stonington Road section leading from Old Mystic was a town road.

In 1947, Route 119 was extended along Main Street (old Route 2) in North Stonington, intersecting Route 2 twice. (I'm not sure if that section was signed.) In 1962, that Main Street section was turned over to the town.

On March 29, 1963, the state reassigned Route 119 to an extended Route 201 and secret SR 627.
