Route 117 is a state highway in southeastern Connecticut, running from Groton to Preston. Route 117 is designated the Colonel Ledyard Highway from its intersection with Route 184 in Groton to the Ledyard-Preston town line.
Route 117 begins at an intersection with US 1 in the village of Poquonnock Bridge in Groton. It starts out as Newtown Road then changes to North Road. About a mile north of US 1, Route 117 has an interchange with I-95 (Exit 88), then continues northward towards the village of Center Groton, where it meets Route 184. There is also access to the Star Plaza shopping area near this junction. Route 117 then enters the town of Ledyard as Center Groton Road.
