Interstate 95 (I-95) is the main north–south Interstate Highway on the East Coast of the United States, running in a general east–west compass direction for 111.57 miles (179.55 km) in Connecticut, from the New York state line to the Rhode Island state line. I-95 from Greenwich to East Lyme is part of the Connecticut Turnpike, during which it passes through the major cities of Stamford, Bridgeport, and New Haven. After leaving the turnpike in East Lyme, I-95 is known as the Jewish War Veterans Memorial Highway and passes through New London, Groton, and Mystic, before exiting the state through North Stonington at the Rhode Island border.
I-95 follows the Connecticut Turnpike from the New York state line eastward for 88 miles (142 km). This portion of the highway passes through the most heavily urbanized section of Connecticut along the shoreline between Greenwich and New Haven, with daily traffic volumes of around 150,000 vehicles throughout the entire 48-mile (77 km) length between the New York state line and the junction with I-91 in New Haven. The turnpike intersects with several major expressways, namely U.S. Route 7 (US 7) at exit 15 in Norwalk, Route 25 and Route 8 at exit 27A in Bridgeport, the Merritt and Wilbur Cross Parkways at exit 38 (via the Milford Parkway) in Milford, and I-91 at exit 48 in New Haven.
I-95 enters Connecticut at its crossing of the Byram River into the town of Greenwich in Fairfield County, where it continues southwest into New York as the New England Thruway. Upon entering Connecticut, the highway is a six-lane freeway known as the Connecticut Turnpike. The road is paralleled by Metro North Railroad's New Haven Line to the northwest, which also carries Amtrak's Northeast Corridor, which it follows for much of its length throughout the state. I-95 heads northeast, passing through the affluent suburban development of the Gold Coast of southwestern Fairfield County and reaching a weigh station in the northbound direction, before turning east-northeast and passing south of downtown Greenwich. The road then heads into the neighborhood of Cos Cob before it crosses over the New Haven Line and the Mianus River, on the Mianus River Bridge. Past the river, I-95 comes to a trumpet interchange which provides access to US 1 between the neighborhoods Riverside and Old Greenwich.
After this interchange, the freeway enters the city of Stamford at the city's West Side. The road crosses the Rippowam River and enters the dense commercial area of Downtown Stamford, where it briefly becomes elevated and serves Route 137 near the Stamford Transportation Center. Upon leaving the downtown area, the freeway passes over the New Haven Line and crosses into the residential East Side of Stamford, where there is an interchange with US 1 that also provides access to Route 106. After this point, the southbound direction gains a fourth lane as the road enters the town of Darien, where there is a service plaza in the southbound direction. In the community of Noroton, the highway passes to the south of Noroton Heights station on the New Haven Line. Near the center of town, the southbound direction narrows to three lanes again, and I-95 has interchanges with US 1 and Route 136. Next, the freeway turns to the northeast, passing over the New Haven Line and coming to a service plaza and welcome center in the northbound direction, before reaching another interchange with US 1.
Immediately after, the road comes into the city of Norwalk in the neighborhood of South Norwalk. The freeway turns east-northeast and passes north of Maritime Aquarium at Norwalk as it comes to an interchange with the southern terminus of US 7 and crosses the Danbury Branch of the New Haven Line within the interchange, before crossing the Norwalk River on the Yankee Doodle Bridge and entering East Norwalk. I-95 enters the town of Westport, just prior to reaching an interchange with the southern terminus of Route 33 and Route 136. Past this interchange, the freeway proceeds to cross over the Saugatuck River and continues to an interchange with the Sherwood Island Connector, which provides access to US 1 and Sherwood Island State Park. The road curves through wooded residential areas, where it comes into the town of Fairfield. Here, I-95 reaches an interchange with US 1/Center Street, which serve the neighborhood of Southport, before crossing the Mill River. Passing to the north of Fairfield Center, the freeway reaches a service plaza in both directions, where there also exists an interchange with Route 135, providing access to the main campus of Fairfield University. From this point, the road curves through an interchange with US 1 on the eastern edge of town.
Following US 1, I-95 enters the city of Bridgeport, which is the largest city in the state of Connecticut. On the city's West Side, the freeway has an interchange with Route 130, where it becomes elevated and gains a fourth southbound lane, as it passes through the industrial areas of the city's southwestern neighborhoods. Within that interchange, the road also crosses the New Haven Line. Further within the area, I-95 crosses over the New Haven Line again and passes to the south of downtown Bridgeport. Here, the freeway provides access to many of the city's major landmarks in the South End and downtown area, and meets southern terminus of Route 25 and Route 8, which both head north from I-95 as a four-lane freeway. From this point, the road narrows to three lanes in the southbound direction, and comes onto to the P.T. Barnum Bridge which carries it over the New Haven Line, adjacent to the Bridgeport station, and the Pequonnock River. On the bridge, the northbound direction gains a fourth lane, as it comes to an exit for Route 127 on Bridgeport's east side, after it passes over Route 130. I-95 reduces back to three lanes in the northbound direction, as it curves into the city's East End, where there is another interchange for Route 130. A short distance later, the freeway reaches an exit to Route 113 on the border of Stratford, providing access to the Sikorsky Memorial Airport. Afterward, the road passes by downtown Stratford and heads into a commercial area, where it has an exit serving US 1 and the southern terminus of Route 110, before crossing the Housatonic River on the Moses Wheeler Bridge.
New Haven County
On the Moses Wheeler Bridge, I-95 crosses into Milford, New Haven County, where it heads into residential areas on the other side of the river. Here, the freeway has a trumpet interchange with US 1, within the village of Devon, before it crosses the New Haven Line and reaches an interchange with Schoolhouse Road/Sub Way, in which the latter road is named for the world headquarters of the Subway restaurant chain. The road continues northeast through wooded areas of the western part of Milford, where it reaches the interchange with the Milford Parkway to the northeast of Downtown Milford. The Milford Parkway, a four-lane limited access parkway, provides access from I-95, as well as US 1 to the Merritt Parkway and Wilbur Cross Parkway, which are both components of Route 15. The freeway enters a reverse turn, where it comes to a cloverleaf interchange with US 1 adjacent to the Connecticut Post Mall, located at the northeastern corner of the interchange. The road heads northeast again into commercial surroundings and passes service plazas in both directions, before coming into the town of Orange, where it reaches an interchange with Marsh Hill Road. The overpass carrying Marsh Hill Road is called the Salemme Memorial Bridge, and the exit provides access to the West Campus of Yale University.
The road passes to the northwest of the university campus as it enters the city of West Haven. Here, I-95 passes mixed areas of suburban development, where it comes to an interchange with Route 162. Thru trucks to Downtown West Haven must use this exit, as trucks may not use the northbound exit ramp at the next interchange, for Campbell Avenue and the southern terminus of Route 122, due to its steep incline. The road makes another reverse turn, where it crosses the New Haven Line and the West River, and comes into the city of New Haven. Immediately after crossing the river, I-95 comes to an interchange with the southern terminus of Route 10, which provides access to the Yale Bowl and connects to Route 34. From this point, the freeway heads northeast, passing the New Haven Harbor in the neighborhood of Long Wharf, before reaching the large interchange complex southeast of Downtown New Haven. The complex includes an interchange with a flyover ramp to M.L.K. Jr. Boulevard serving the downtown area, as well as the highway's split with I-91, which heads north-northeast from I-95 towards Hartford. Past I-91, the freeway turns southeast to cross the Quinnipiac River on the Pearl Harbor Memorial Bridge, locally known as simply the "Q Bridge". On the other side of the bridge, the road heads into another area of mixed development in The Annex neighborhood. Here, I-95, expands to four lanes in the southbound direction, and has an interchange with the northern terminus of Route 337, that also provides access to Tweed New Haven Airport.
Past this interchange, the freeway enters the town of East Haven, where US 1 parallels the highway on the both sides as a frontage road as the southbound direction narrows back to three lanes, before coming to a partial interchange with that route. Within the interchange, it also crosses the Northeast Corridor. A short distance later, there is a southbound exit and northbound entrance with Route 100 before the road curves east across Saltonstall Mountain and Lake Saltonstall, and comes into the town of Branford. Within this area, I-95 passes through the Stewart B. McKinney National Wildlife Refuge where it comes to an northbound exit and southbound entrance with the Branford Connector, that connects to US 1, Route 142, and Route 146 near Short Beach. Just after the connector, there is a service plaza in both directions, and the freeway passes north of the center of Branford. From here, the road narrows to four lanes and continues east into more rural and wooded surroundings, coming to an interchange with US 1 on the east side of town. I-95 briefly enters a commercial area and passes north of the Stony Creek neighborhood. The freeway heads back into wooded areas as it enters the town of Guilford, where it comes to interchanges with US 1 and Route 77 north of Guilford Center. The road continues east across the East River marshlands, and comes into the town of Madison prior to crossing the Neck River. The road heads to the north of Madison Center, where it has an interchange with Route 79 with a park and ride lot in its northeastern corner. Past Route 79, I-95 passes service plazas in both directions, and reaches an interchange with the Hammonasset Connector, which provides access to Hammonasset Beach State Park. At this point, the route crosses over the Hammonasset River and leaves New Haven County.
Middlesex and New London counties
Upon crossing the river, I-95 comes into Clinton, Middlesex County continuing east through rural surroundings with some suburban elements. The freeway reaches an interchange with Route 81, close to the center of town adjacent to the Clinton Crossing Premium Outlets outlet mall, to the northwest of the interchange. From here, the road makes a reverse turn across the Menunketesuck River, after which it enters the town of Westbrook and reaches an interchange with Route 145. At this point, I-95 makes another reverse turn before turning east again, at the interchange with Route 153 that also provides access to the Westbrook Outlets outlet mall, just north of Westbrook Center. The freeway then reaches a pair of roadside stops, in which the northbound direction has a rest area and welcome center, and the southbound direction has access to Troop F of the Connecticut State Police, just before coming to the interchange for Route 166, where it enters the town of Old Saybrook. Within Old Saybrook, the road turns northeast, and has an interchange with Route 154 northwest of Old Saybrook Center. On the east side of town, US 1 merges onto northbound I-95 and joins the route in a concurrency, as it widens to six lanes, and comes to a trumpet interchange with the southern terminus of Route 9, which heads northwest from I-95/US 1 as a four-lane freeway parallel to the Connecticut River, towards Greater Hartford. A short distance later, the two routes cross the Raymond E. Baldwin Bridge, that has a fourth southbound lane, over the Connecticut River.
On the crossing of the Connecticut River, I-95/US 1 comes into Old Lyme, New London County and immediately narrows to three southbound lanes, as it reaches the interchange with Route 156, where US 1 exits the highway and the concurrency ends. The freeway reduces to four lanes and heads into a heavily forested area with little development around the highway, where it crosses the Duck River. The road crosses the Threemile River prior to crossing the Fourmile River, as it enters the town of East Lyme. I-95 immediately comes to a trumpet interchange with the Rocky Neck Connector, that provides access to the Rocky Neck State Park. Continuing northeast through the center of East Lyme, the freeway enters into areas of mixed development with suburban elements before crossing the Pattagansett River within its interchange with Route 161, in the village of Flanders. Shorty afterward, there is an interchange with US 1, and the road crosses the Niantic River just before meeting the southern terminus of I-395. Here, the Connecticut Turnpike splits to the northeast along I-395, which heads toward Worcester, Massachusetts.
Past I-395, the freeway becomes the Jewish War Veterans Memorial Highway and enters the town of Waterford. A short distance later, the road heads into suburban-like commercial areas. I-95 interchanges with Route 85 before entering the city of New London as it gains a third northbound lane and a frontage road. Running north of the downtown area and the New London Waterfront District, the freeway meets Route 32. Past this interchange, US 1 merges onto northbound I-95, and the two routes turn east to run concurrent across the ten-lane Gold Star Memorial Bridge over the Thames River, where the highways come into the town of Groton. Before the end of the bridge, US 1 exits the highway, providing access to Downtown Groton. The freeway narrows to six lanes as it reaches an interchange with Route 12 and the western terminus of Route 184, which also provides access to the Naval Submarine Base New London. A short distance later, the road reverse turns through a directional interchange with the northern terminus of Route 349, which spurs into the downtown area. Past Route 349, the median widens, after many miles of having a jersey barrier in the middle of the highway, and it heads into forested surroundings. In the eastern part of Groton, I-95 interchanges with Route 117, leading south to the village of Noank and north to the town of Ledyard. From here, the freeway passes a northbound scenic overlook, and crosses the Mystic River.
Upon crossing the Mystic River, the road enters the town of Stonington, where it comes to an interchange with Route 27 within the village of Mystic, that provides access to Mystic Seaport as well as the Olde Mistick Village shopping mall and the Mystic Aquarium located at the southeastern corner of the interchange. At this point, I-95 reduces to four lanes, and turns northeast past wooded areas with some residences, and comes to an interchange for Route 234 north of the center of Stonington, with a park and ride lot being located in the northwest corner of the interchange. From here, the freeway continues northeast to an interchange for Route 2/Route 49, providing access to the village of Pawcatuck to the south and a park and ride lot to the north in the middle of the interchange. Also, within the interchange, the southbound direction has a rest area and welcome center and the road comes into the town of North Stonington. I-95 continues to its last exit in Connecticut, the interchange with Route 216 and the eastern terminus of Route 184, as the median narrows. Immediately after this interchange, the freeway leaves Connecticut and continues as a four-lane freeway northeast into Rhode Island towards Providence.
I-95 in Connecticut has far more exits than typical Interstate Highways, particularly in Fairfield and New Haven Counties, with some exits less than one mile (1.6 km) apart. State transportation officials have said that the reason for the many exits stems from the state's original justification for building parts of the highway—to ease traffic congestion on US 1 by providing a faster alternate route, even for drivers traveling short distances within the same community. To overcome potential opposition to the highway from towns through which the route would traverse, the state agreed to guarantee each affected town a certain number of access points to the highway. Rather than skirting urban areas, the highway was built directly through the most dense sections of Stamford, Norwalk, Bridgeport, and New Haven.
While most of I-95 was built as the Connecticut Turnpike, the route incorporated several pieces of already-built relocations, some to freeway standards, of US 1 (the turnpike split from the US 1 relocation in East Lyme, along the Old Lyme-New London section):
- Darien bypass, opened c. 1952
- New Haven east of the Quinnipiac River, opened c. 1951
- Old Saybrook-Old Lyme, Raymond E. Baldwin Bridge over the Connecticut River and approaches, opened 1948
- Old Lyme-New London, opened by 1950 as a two-lane road
- New London-Groton Gold Star Bridge over the Thames River and approaches, opened 1943
Other improvements in the corridor included the New York-Meriden Merritt Parkway/Wilbur Cross Parkway, New Haven-Old Saybrook Route 80, and Groton-Rhode Island Route 184, the latter connecting in Rhode Island to Route 3, a shortcut to Providence.
Most of the turnpike opened January 2, 1958, and was designated I-95 south and west of the split with the relocated US 1 by 1959. The rest of I-95 from I-395 to the Connecticut–Rhode Island border opened December 12, 1964. The Gold Star Bridge was twinned c. 1975, along with a reconstruction of its approaches, and in 1993 the Raymond E. Baldwin Bridge was replaced with a wider span.
The state installed cameras to watch traffic along the highway in the early 1990s. As of 2007, about 100 cameras have been set up and are monitored by state police and the Connecticut Department of Transportation (ConnDOT). In Fairfield County, local emergency responders (fire departments and ambulance services) that serve the highway in individual towns have asked for direct feeds from the cameras to avoid mistakes. When travelers report an accident, they sometimes tell authorities that it occurred near an exit that is actually not the nearest to the scene, slowing down response time. The traffic feed from the cameras is available on the World Wide Web, but the service can be spotty, according to the Stamford and Norwalk fire chiefs, who said they were hoping that a proposed $40 million upgrade of the camera system, under consideration by the state in 2007, would provide them access. Feeds from these cameras are also used by local media outlets, as part of traffic report segments in news programming, and in some instances as a part of a designated traffic and weather channel.
In January 1983, a truck with a brake failure slammed into a line of cars waiting to pay a toll on I-95 in Stratford; seven people were killed. This accident helped lead to the removal of toll barriers throughout Connecticut, which was completed six years after.
On the morning of June 28, 1983, a 100-foot (30 m) section of the Mianus River Bridge in Cos Cob collapsed, plunging northbound I-95 traffic into the Mianus River below, killing three. The collapse was blamed on the failure of the steel pins to hold the horizontal beams together and inadequate inspection prior to the collapse. Northbound traffic was diverted on this section of I-95 for 25 days. Southbound traffic was unaffected.
On March 26, 2004, a bridge on I-95 in Bridgeport was partly melted by the explosion of a tanker truck carrying over 11,900 US gallons (45,000 l) of fuel oil. Repairs were estimated to take at least two weeks, but the highway was opened to northbound traffic in only a few days. Southbound traffic resumed about a week later after a temporary bridge was installed to carry traffic while the destroyed bridge was rebuilt.
At 10:20 a.m. on November 2, 2007, a tanker truck carrying heating oil plowed over the divider, knocking the side of a tractor trailer and striking several other cars in its path. Three people were killed, including the driver of the tanker and the occupants of two cars that were completely destroyed in the crash. The driver of the tractor trailer survived (his canine companion emerged completely unharmed) but the trailer was split open. At least three other cars were involved in this accident. A part of the road was damaged and took until the next morning to fully reopen, partly due to a cleanup after the accident.
While the corridor was designated "High Priority Corridor 65" in 2005, work along Interstate 95 in Connecticut has been ongoing for nearly 30 years.
Interstate upgrades include:
- Replace the bridge over the Connecticut River in Saybrook (completed in 1993)
- Replace the bridge over the Saugatuck River in Westport (completed in 2001)
- Widening and reconstruction of I-95 through Bridgeport (completed in 2006)
- Upgrade the median divider from New York state line to Waterford to meet current safety standards (segmented construction ongoing since 1993)
- Construction of a new extradosed Q Bridge (Pearl Harbor Memorial Bridge) over the Quinnipiac River (completed in 2015)
- Reconfiguring the interchange between I-91, I-95, and Route 34 in New Haven (completed in 2016)
- Replace bridge over the West River in New Haven (completed in June 2018). Exit 44, southbound, was closed in April 2015, and the remaining ramps at Exit 45, northbound, and southbound were realigned and renumbered Exit 44.
- Reconstruct I-95/I-395 interchange in Waterford to accommodate proposed Route 11 Expressway connection (proposed).
- Replacement of the Moses Wheeler Bridge over the Housatonic River (underway)
- Widening and reconstruction of I-95 between Norwalk and Stamford — in December 2007 a 15-month, $5.5 million project was completed to add fourth (or "operational") lanes in each direction between the entrances and exits at exits 10 and 11 in Darien. This project was completed in 2007. A similar project between exits 11 and 13 began in 2008 and was completed in 2010. An earlier project added a fourth lane on the southbound side from the entrance at exit 10 to exit 8. After that lane was added, a ConnDOT study concluded that accidents were down on that stretch of the highway by 20 percent, amounting to about 160 fewer accidents per year.
- Widen I-95 mainline from Branford to the Rhode Island state line (proposed)
- Adding an operational lane between exits 14 and 15 in Norwalk (completed in 2016)
- From 2011 to 2015, all 10 of the service plazas along I-95 were rebuilt (pairs of plazas are located in Darien, Fairfield, Milford, Branford, and Madison, with a separate plaza for each direction of I-95). All of the renovated plazas feature modernized Mobil gas stations, Alltown convenience stores, Dunkin Donuts, and Subway shops. McDonald's is also available at eight of the ten plazas, while the largest plazas additionally feature Sbarro, Panda Express and various other quick-service options. The last of the plazas to be rebuilt, southbound in Madison, opened in August 2015.
Mass transit upgrade projects have been undertaken in large part to reduce traffic on the highway, which is often congested, particularly in Fairfield County:
- New train station near the Fairfield–Bridgeport city line (completed in 2011, fully operational in January 2012)
- Intermodal Transportation Center in Bridgeport (completed)
- New train station in West Haven (completed)
- Upgrade catenary power lines along the New Haven Line (underway through the 2010s)
- New train station in Madison (completed)
- Purchase new railroad cars and refurbish existing cars to increase capacity and reliability
- Construct new container barge ports at Bridgeport and New Haven
- Expansion of freight service on the New Haven Line
- Replace outdated bridges and straighten various sections of the New Haven Line to allow higher operating speeds for Amtrak and Metro-North trains
Exit numbers are currently sequential, but will be changed to mileage-based in the future.
