Encyclopedia
Route 80 is a 25.91 miles (41.7 km) long secondary east–west state route in Connecticut
from New Haven
to Deep River
. It serves as a more inland alternate route to US 1
in eastern New Haven County and Middlesex County.
and Route 17
in New Haven (at Exit 8). Route 17 splits off and heads northward right after the exit. Route 80 begins as a 4-lane principal arterial road in New Haven, East Haven
and North Branford
, where it overlaps Route 22 for 1.5 miles (2.4 km). It becomes 2 lanes from North Branford to Madison
. From Killingworth
to its terminus in Deep River, it becomes a rural minor arterial road. In Deep River, Route 80 briefly overlaps Route 145
, then has an interchange with Route 9
about 0.6 mile (0.965604 km) before its terminus at Route 154.
Route 80 crosses over the Hammonasset River
between Madison and Killingworth on Bridge No. 1132
, a historic open-spandrel arch bridge built by the Connecticut Highway Department in 1934.
at the Guilford-Madison town line northeast through Killingworth center, then east to Deep River, ending at the Middlesex Turnpike. The turnpike, known as the Pettipauge and Guilford Turnpike, used Green Hill Road in Madison then modern Route 80 to Deep River. In 1824, another turnpike was built, beginning in the Fair Haven
section of New Haven
, heading eastward along modern Route 80, and ending at the Pettipauge and Guilford Turnpike in Killingworth center. This was known as the Fairhaven Turnpike.
In 1922, when Connecticut first publicly signed its state highways with route numbers, several new numbered routes where created from these two turnpikes. From Fair Haven to North Branford center, State Highway 135 was created. Old Highway 135 continued south from North Branford center along modern Route 139 to the Boston Post Road. The eastward continuation of the old Fairhaven Turnpike between North Branford center and the village of North Guilford was designated as State Highway 140. The portion of the old Pettipaue and Guilford Turnpike between Killingworth center and Deep River center became State Highway 175.
Modern Route 80 was established as part of the 1932 state highway renumbering
from old highways 175, 140, and the east–west portion of 135. In 1940, its east end was relocated to US 1 in Old Saybrook
along Warsaw Street, Main Street, Middlesex Turnpike, and Essex Road. In the 1950s, it was extended west to Route 10
in New Haven along Middletown Avenue, State Street, Edwards Street, Munson Street, and Henry Street to Route 10 (Sherman Avenue). In 1962, the western end was truncated to its current location at Route 17. In 1966, with the opening of Route 9, the eastern end of Route 80 was truncated and rerouted to its current location.
