Route 57 is a secondary state highway in western Connecticut serving as the "Main Street" of and connecting the towns of Westport and Weston. The road continues north through Redding to end at US 7 just after crossing into Wilton.

Route 57 begins as Kings Highway North at the west bank of the Saugatuck River at an intersection with Route 33 north of downtown Westport. After crossing the river, it turns north onto Canal Street then onto Main Street. Route 57 overlaps Route 136 for 0.3 mi (0.48 km) between Compo Road North and Weston Road. Route 57 then turns onto Weston Road as it intersects with the Merritt Parkway at an interchange (Exit 42). Continuing north, Route 57 crosses over the Aspetuck River and Saugatuck River before crossing into the town of Weston. Route 57 continues through Weston center, where it briefly overlaps Route 53. Past Weston center, the road becomes Georgetown Road and proceeds for another four miles (6 km) through Weston until it reaches Route 107 just across the town line in Redding. Route 57 then turns west along Route 107 (Redding Road and School Street), overlapping it for 0.3 mi (0.48 km) into the Georgetown section of the town of Wilton. Routes 57 and 107 end concurrently at US 7 in Georgetown.
