The general route and construction of the turnpike were both mandated by state law. Intended to relieve congestion on
US 1 and
Route 15 (the
Merritt and
Wilbur Cross parkways), design work began in 1954. The Connecticut Turnpike opened to traffic on January 2, 1958, at 2:30 p.m. However, the westernmost portion of the highway (the connecting
Greenwich with the
New England Thruway) opened 10 months later. Tolls were originally collected through a series of eight toll booths along the route. The Connecticut Turnpike was designed and built much differently than other toll roads built around the same time. Unlike toll roads in other states that operated under semi-autonomous, quasi-public toll road authorities, the Connecticut Turnpike was operated by the Connecticut Highway Department (later the Connecticut Department of Transportation) from its inception. Additionally, unlike toll roads in other states where revenues collected from motorists were legally required to be kept within the toll road authority and used to finance the facility's construction and upkeep, toll revenues from the Connecticut Turnpike were placed into the state's general fund and used for highway and non-highway expenditures alike. Finally, the closely spaced interchanges and eight mainline barriers were a result of each town through which the Connecticut Turnpike passed being guaranteed a certain number of access points to gain the support of each affected town for construction of the highway. This is in contrast to toll roads built in neighboring states with widely spaced interchanges that normally featured a ticket system where one obtained a ticket at entering the toll road, then paid a distance-based fare upon exiting. The turnpike was renamed after former Connecticut Governor
John Davis Lodge on December 31, 1985, two months after the tolls were removed. Local legend is the initial phase of turnpike construction in 1954 was so disruptive in heavily Republican
Fairfield County that local voters there turned on incumbent Republican Governor Lodge, leading to his defeat by
Abraham Ribicoff. Initially, the Connecticut Turnpike was signed as an east–west route, even after the I-95 designation was added to the turnpike between Greenwich and Waterford in the early 1960s. Signs indicating I-95/Connecticut Turnpike as an east–west route existed in places until the early 1990s, when the remaining east–west signage was replaced by north–south signage. From Waterford to Killingly, the turnpike was initially designated as Route 52 in 1967, following the opening of the toll-free section of Route 52 from Killingly to the Massachusetts border. To accommodate the truncation of the Hartford to Providence extension of I-84 to Killingly, following Rhode Island's cancellation of its portion of that extension in the early 1980s, Route 52 was to be re-designated as an Interstate. Initially, Connecticut and Massachusetts requested that the
American Association of State Highway and Transportation Officials (AASHTO) extend the
I-290 designation southward along free Route 52 and the Connecticut Turnpike to I-95 in Waterford. AASHTO rejected the I-290 request and instead approved the I-395 designation in 1983.
Accidents Several notorious accidents have occurred throughout the turnpike's history. The worst of these was a
serious incident on January 19, 1983, in which a
tractor trailer after a brake failure collided with four cars at the
Stratford toll plaza, killing seven people and injuring several others. The investigation following the crash determined that the truck driver fell asleep at the wheel just before the crash took place. At the time, the government of Connecticut was removing tolls along the turnpike; as a result of the incident, the government expedited the removal of the remaining tollbooths. In June 1983, a section of the turnpike's northbound
Mianus River Bridge in Greenwich collapsed due to corrosion of its substructure, killing three motorists crossing it at the time. On March 25, 2004, a tanker truck carrying fuel swerved to avoid a car that cut the truck off and subsequently overturned, dumping of home heating oil onto the Howard Avenue overpass in
Bridgeport. Passing vehicles kicked up the oil which ignited a towering inferno that subsequently melted the bridge structure and caused the southbound lanes to sag several feet. The northbound lanes, which received less damage from the fire, were opened five days later after being reinforced with temporary scaffolding. The southbound lanes opened on April 1, after a temporary bridge was erected.
Stalling of upgrades by budget deficits and lawsuits The Connecticut Turnpike opened southwest Connecticut to a mass migration of New Yorkers, leading to substantial residential and economic growth in
Fairfield and
New Haven counties. The turnpike became a primary commuter route to
New York City. With additional segments of I-95 that opened in the 1960s connecting to
Providence and
Boston, the turnpike became an essential route for transporting people and goods throughout the
Northeast. As a result, much of the turnpike had become functionally obsolete by 1965, with traffic exceeding its design capacity. Originally designed to carry 60,000 vehicles per day (VPD) on the four-lane sections and 90,000 VPD on the six-lane portion west of New Haven, the turnpike carried 75,000–100,000 VPD east of New Haven, and 130,000–200,000 VPD between New Haven and the New York state line as of 2006. There were dozens of plans discussed to alleviate traffic congestion and improve safety on the turnpike over the past half-century, but most of these plans languished amid political infighting and lawsuits brought on by special-interest groups. Still, traffic and deadly accidents continued to increase each year on the turnpike, and by the 1990s the Connecticut Turnpike had started to become known as "the Highway of Death". Furthermore, while most of the turnpike is signed as I-95 or I-395, the highway was designed and built before the
Interstate Highway System was established. As a result, much of the turnpike does not meet Interstate standards, particularly with overpasses ranging from ;
Interstate Highway standards require a minimum of of vertical clearance. Interchanges are too closely spaced; ramps and acceleration-deceleration lanes need to be lengthened. In some areas, median and shoulder widths and curve radii also fall short of Interstate standards. Complicating efforts to upgrade the turnpike to Interstate standards is that engineers did not acquire enough
right-of-way to accommodate future expansion when the Connecticut Turnpike was built during the late 1950s, which means adjacent land must be seized to upgrade the turnpike, resulting in lengthy and costly
eminent domain battles between the State of Connecticut and landowners refusing to give up their property. Additionally the turnpike passes through areas with some of the highest property values in the country, making land acquisition for expanding the highway extremely expensive. Finally, the turnpike was built through environmentally sensitive ecosystems and wetlands associated with
Long Island Sound, meaning most expansion projects require lengthy environmental impact studies that are able to withstand constant litigation by environmental groups. Air pollution laws also cause conflict, since Connecticut is grouped into the federal statistical areas around New York City and it suffers from consequences and special regulations applied to non-compliant air quality areas. An example of this is that it is easier to lengthen an entrance or exit ramp than to add a full lane, since adding any capacity to a road, by definition, will increase the pollution created by the road, further violating federal air quality standards. In 2000, one CTDOT official commented during a public meeting on expanding
I-84 (an Interstate that parallels I-95 about further inland), "If we had tried to build I-95 today, it would be impossible because of the sensitive ecosystems it passes through. It would never get approved."
Bridge collapse jumpstarts turnpike upgrades A comprehensive plan to address safety and capacity issues on the Connecticut Turnpike did not progress beyond the initial planning stages until the collapse of the
Mianus River Bridge on June 28, 1983. Following the collapse, Governor
William A. O'Neill initiated an $8 billion program to rehabilitate Connecticut's highways. Included in this program was the inspection and repair of the turnpike's nearly 300 bridges and overpasses. Furthermore, O'Neill directed ConnDOT to develop a viable plan for addressing safety and congestion on the state's roads.
High-priority status Throughout the late 1980s and early 1990s, CTDOT developed a comprehensive plan to improve the turnpike through Fairfield and New Haven counties. In 1993 CTDOT embarked on a 25-year multibillion-dollar program to upgrade the Connecticut Turnpike from the
Connecticut River at
Old Saybrook to the New York state line at
Greenwich. The program included the complete reconstruction of several turnpike segments, including replacing bridges, adding travel lanes, reconfiguring interchanges, upgrading lighting and signage, and implementing the
intelligent transportation system with traffic cameras, a variety of embedded roadway sensors, and
variable-message signs. Since the start of the program, a section through
Bridgeport was completely rebuilt to Interstate standards. In 2015, a long-term $2 billion program was completed, to rebuild of turnpike between
West Haven and
Branford, including a new extradosed
Pearl Harbor Memorial Bridge over the
Quinnipiac River and
New Haven Harbor. Plans to upgrade the turnpike received a boost in 2005 when federal legislation known as
SAFETEA-LU designated the I-95 portion of the Connecticut Turnpike from the New York state line to
Waterford as
High Priority Corridor 65. Corridor 65 also includes the section of I-95 from Waterford to the Rhode Island state line that was built in 1964, which is not part of the Turnpike.
Plans for the I-395/SR 695 section Traffic is relatively light on the rural I-395 section and the northeast leg (SR 695) in Killingly; this section is largely unchanged from its original 1958 profile. The only two major projects completed on this section since were the 2015 renumbering of exits based on I-395 mileposts (exit 77 became exit 2, up to exit 90 which became exit 35) and the reconstruction of the northbound on and off ramps at exit 11 (old exit 80) in
Norwich, completed in 2009.
