Connecticut Route 243

Route 243 begins in the Westville neighborhood of New Haven as Fountain Street branching from Whalley Avenue (Route 63 towards the west, while Whalley Avenue continues northwest). Fountain Street passes by the Westville Post Office then continues through the residential part of Westville. Along the way, it intersects Route 122 (Forest Road and Dayton Street). Fountain Street continues west, going under the Wilbur Cross Parkway (does not have an interchange with it) into the town of Woodbridge. Within Woodbridge, it intersects with Woodfield Road, which provides access to the Woodbridge Country Club. Route 313 (Rimmon Road) begins near the country club, heading directly for the town of Seymour. After the junction with Route 313, the road changes name to Ansonia Road. About 1.6 miles (2.6 km) later, it intersects with Route 114 (Racebrook Road), which leads to Orange (south) and Woodbridge center (north). Route 243 then enters the city of Ansonia, just north of the Derby city line. Within Ansonia, the road becomes known as Pulaski Highway. At the end of the road, Route 243 then turns left on Prindle Avenue, right on Platt Street, and left on Elm Street, finally ending at Route 115 (Main Street), south of downtown Ansonia near the Derby line. Across Main Street, the road becomes Division Street, an unsigned state highway connector across the Naugatuck River that connects to Pershing Drive (SR 727) in Derby. Division Street has the unsigned designation SR 853.[1]

Fountain Street was originally part of a 19th century turnpike known as the Rimmon Falls Turnpike. The old turnpike connected New Haven and Seymour via modern Route 313 and Fountain Street. In 1932, Route 114, connecting Route 63 in Woodbridge (then part of Route 67) to Woodbridge Center and then ending back at former Route 67 in Westville, was established along Center Road, Racebrook Road, and Ansonia Road/Fountain Street. In 1951, the southern leg of Route 114 was relocated to end at Route 1 in Orange instead. The Ansonia Road/Fountain Street portion of old Route 114 became an unnumbered state road. Route 243 was established in 1963 from this piece of old Route 114 and the westward continuation of Ansonia Road/Pulaski Highway, which was also an unnumbered state road.[2]

The entire route is in New Haven County.
