An 0.4-mile segment of Route 317, from Route 67 to Painter Hill Road, is a state scenic road. The Danbury News-Times wrote:

A favorite stop for photographers, antiquers and pumpkin pickers alike, this short (.4 miles), but scenic country road runs through the town of Roxbury. Rolling hills and fields provide the perfect backdrop for barns and homes - many over a century old.

CT 317 History

In the 1920s, state highway 317 followed Silver Lane (today's SR 502).

A small part of today's Route 317 – Sycamore Avenue between Bear Hill Road and US 6 – was SR 517, a designation that possibly dates back to 1932.

In 1960, the state Committee to Reclassify All Public Roads recommended adding a continuous state route from Roxbury to Woodbury along Church Street and Good Hill Road. In 1962, SR 517 was extended along this route. In 1964, SR 517 was promoted to signed Route 317.
