- Length 22.76 miles
- From SR 841 (Downs Street) in Danbury
- To Route 55 in Sherman
To the motorist, Route 39 begins where seven other highways intersect: SR 841, Route 37, Route 53, and the state's only four-way overlap: I-84, US 6, US 7, and US 202.
Route 39 not only intersects, but crosses Route 37 twice. No two other state highways cross twice.
Also, at New Fairfield Center, where 37 and 39 cross, there are two short side streets called Old Route 37 and Old Route 39.
In Afghanistan, 39 is considered unlucky – and not because of one of its famous divisors.
CT 39 History
Commissioned in 1932, Route 39 originally extended about 13.6 miles from Route 55 in Sherman to Route 37 in New Fairfield center. South of there, the road to Danbury was called Route 100.
In 1934, Route 37A was created, taking over most of Route 100; and Route 39 was extended along Ball Pond Road and Milltown Road to the New York state line, for a length of 18.61 miles. The Milltown Road portion, which had not been part of Route 100, was formerly unsigned SR 464.
In 1963, Route 37A was deleted. Route 39 was rerouted and extended over most of Route 37A to Danbury. The leftover portion of old Route 39 (Milltown Road), long ago SR 464, became SR 839.
