Route 53 begins at US 1 in Norwalk and travels through the towns of Norwalk, Wilton, Weston, Redding, and Bethel. Route 53 ends in Downtown Danbury at a quadruple junction with Routes 37, 39, and a secondary state road leading to Interstate 84. A section in Redding, running from the Weston town line to the beginning of a brief concurrency with Route 107, is a designated state scenic road.
History
The main road connecting the city of Norwalk to the borough of Newtown was organized as a private turnpike in May 1829. Known as the Norwalk and Newtown Turnpike, or more commonly as just the Newtown Turnpike, the road mostly used modern Route 53 from Norwalk to the Saugatuck Reservoir in Redding. Northeast of the reservoir, the old Newtown Turnpike continued the straight route using what are now town roads to Route 302 in the Dodgingtown section of Newtown, then Route 302 into Newtown borough. The portion of modern Route 53 between the West Redding section of Redding and Bethel center was the northern half of the Norwalk and Danbury Turnpike. This turnpike was chartered in 1795 and used part of modern US 7, modern Route 107, and Umpawaug Road to West Redding, then continued on modern Route 53. Between Redding center and West Redding, modern Route 53 was the northern half of the Northfield Turnpike, which was chartered in 1826. The southern half is now Valley Forge Road and Lyons Plains Road. In 1922, part of the Norwalk and Danbury Turnpike between West Redding and Bethel was given the designation State Highway 180 while part of the Newtown Turnpike between Redding Ridge and Newtown was assigned as State Highway 158. Route 53 was first defined in the 1932 state highway renumbering between Weston center to Georgetown along Georgetown Road, then along Redding Road to West Redding, then along former Highway 180 to Bethel. In 1954, the southern end was relocated and now ended at US 7 in Wilton. Route 57 took over the former Georgetown Road segment and the Newtown Turnpike became unsigned SR 725. In 1963, the southern part was relocated onto the Newtown Turnpike to Weston Center, then shifted to the alignment of former Route 103 via Cedar Road/Norfield Road. In 1973, Route 53 took over former US 202 to Downtown Danbury when US 202 was relocated to a new alignment.
