The 'New York State Thruway' (officially the 'Governor
Thomas E. Dewey Thruway') is a limited-access
toll highway in the
U.S. state of
New York. Built in the
1950s by the State of New York in order to connect the major cities of New York, it is the longest toll road in the United States, with the 496.00 mile (798.23 km) mainline extending from the
Pennsylvania/New York State border in the west to
the Bronx in the east. In
1958 it was incorporated into the
Interstate Highway System as portions of
Interstate 87,
Interstate 287,
Interstate 90,
Interstate 84, and
Interstate 190. It is operated by the 'New York State Thruway Authority' (NYSTA).
Only three sections of the Thruway system are not part of the Interstate Highway System. One such section is the
Garden State Parkway Connector, which branches from the Thruway mainline at exit 14A in
Spring Valley to connect to the Garden State Parkway at the New Jersey state line near
Montvale. Another section is located on the Thruway mainline within exit 24 in
Albany, as the mainline is unnumbered for a brief distance between the point where
Interstate 87 departs the roadway and
Interstate 90 enters it. The third section, the longest such section on the Thruway, is a six-mile portion of the Berkshire Connector, which has no Interstate designation between exit 21A on the Mainline in
Selkirk and exit B1 in
Schodack, where the Berkshire Connector merges with I-90.
Of the 641.29 miles in the Thruway system, 632.31 miles (98.6%) carries at least one Interstate designation.
Interstate 90, which comprises the bulk of the mainline and the Berkshire Connector, runs for 365.55 miles along the Thruway, including 17.70 miles as part of the Berkshire Connector and 347.85 miles on the mainline.
Interstate 87 comprises the remaining 148.15 miles of the mainline, including an 18.86 mile long
concurrency with
Interstate 287 north of New York City.
Interstate 84 covers another 71.46 miles, including the
New York State Bridge Authority-maintained
Newburgh-Beacon Bridge, while Interstate 287 spans 29.76 miles (including the 18.86 miles shared with I-87),
Interstate 190 lasts for 21.24 miles and
Interstate 95 covers 15.01 miles.

Route description
The New York State Thruway system is a collection of seven individual components across the state of
New York, with the 496 mile long mainline as the centerpiece. The system connects New York to four neighboring states (
Connecticut,
Massachusetts,
New Jersey, and
Pennsylvania) as well as the
Canadian province of
Ontario.
All highways maintained by the NYSTA lack the green
reference markers that exist on all
New York State Department of Transportation-maintained roads, as would be expected. In their place, NYSTA-controlled roadways use small, square tenth-mile markers with a white background and blue numbering. These markers differ from those used by NYSDOT on
limited-access highways as state-maintained expressways typically feature tenth-mile signage similar to that used in the remainder of the
United States while
state routes utilize the reference markers, which display mileage information on their third row.
Except on the mainline, mile markers on NYSTA-maintained roads bear the Thruway logo on the top and an identifier for that highway, such as an I-84 shield for
Interstate 84 and the letters "CW" for the Cross-Westchester Expressway (
Interstate 287). Mainline mile markers feature only the word "mile" and the current milepost of the Thruway in relation to New York City.
Mainline

Advance signage for exit 45 (
I-490).
From west to east, the Thruway begins as Interstate 90 along
Lake Erie on the
Pennsylvania border in
Chautauqua County. It follows the lake shore northeast and passes along the far western side of
Cheektowaga, a large
suburb of
Buffalo directly east of the city. Across upstate New York, it roughly parallels the route of cross-state railroad tracks, which in turn follow the
Erie Canal, passing north of
Batavia, south of
Rochester, north of
Syracuse, and north of
Utica before following the valley of the
Mohawk River to
Albany.
South of Albany, it continues as the southern portion of Interstate 87, roughly paralleling the
Hudson River to the river's west, passing near
Kingston,
New Paltz, and
Newburgh. In
Harriman, the major closed ticket system comes to an end at the
Woodbury toll barrier, located on the mainline within exit 16 (
New York State Route 17), a
trumpet interchange. Along with the mainline barrier in Harriman, a separate toll plaza exists on the exit 16 ramp midway between the Thruway and NY 17 exit 131 (
New York State Route 32). To distinguish between exit 16 and the Woodbury toll barrier, Thruway tickets list the NY 17 interchange as exit 16 and the Woodbury toll plaza as exit 15, although the actual exit 15 is situated almost 15 miles to the south.
Northbound traffic on I-87 traveling through the Woodbury toll barrier is given a ticket stamped for exit 15 while travelers on southbound I-87 must surrender their ticket and pay the appropriate toll. Traffic heading south on I-87 and exiting at exit 16 must pay the appropriate toll for exit 16 at the Harriman toll plaza. Traffic heading north on I-87 and exiting at exit 16 must pay a fixed-rate toll at the Harriman plaza. Traffic entering the Thruway from NY 17 east must pay a fixed-rate toll at the Harriman barrier and, if traveling north, collect a discounted ticket stamped exit 16 at the Woodbury barrier. The ticket is identical to that given for exit 15 with the exception that the toll for exit 16 is subtracted from all of the prices.

Suffern.
South of Harriman, the Thruway follows the valley of the
Ramapo River until its junction near the
New Jersey border with
Interstate 287, which it joins, then cuts east across
Rockland County. It connects with the New York segment of the
Garden State Parkway then crosses the Hudson on the
Tappan Zee Bridge. On the east side of the Hudson it continues south through
Westchester County to the Bronx. The exit numbering system begins at the Bronx/Westchester County line with exit 1 and ends with exit 61 at the Pennsylvania/New York border.
The highway employs both open-system and closed-system tolling. From the Bronx/Westchester County line to the
New York State Route 17 exit, an open system (coin-drop) is used. From there northward, a closed system is employed where drivers must obtain tickets which show their point of entry and the cost of traveling from there to their desired point of exit. Upon exiting the Thruway, the ticket must be surrendered and the appropriate toll must be paid. Two separate closed systems are used on the Thruway mainline; one between NY 17 and Buffalo (with an inclusive spur route) and another from Buffalo to Exit 61.
Berkshire Connector
The Berkshire Connector is a 24.28 mile long east-west spur connecting the Thruway mainline to the
Massachusetts Turnpike. The connector is enclosed within the mainline's major closed system, so traveling between the mainline and the Connector via exit 21A does not involve crossing a toll barrier, and the connector's exits up to the end of the closed system past exit B2 are listed with the mainline exits on tickets for the major closed system.
The spur separates from the Thruway at exit 21A in
Selkirk, south of
Albany, and proceeds east over the
Castleton Bridge, crossing the
Hudson River, before navigating through the southernmost portion of
Rensselaer County. In
Schodack, the Connector meets
Interstate 90 at exit B1. I-90 joins the Berkshire Connector, following the spur east into
Columbia County.
Unlike the Rensselaer County segment, which runs east-west, the Berkshire Connector in Columbia County takes on a northwest-southeast alignment as the roadway heads toward
Massachusetts. In
East Chatham, I-90 and the Connector interchange with the northern terminus of the
Taconic State Parkway at exit B2. Two miles to the southeast, the closed ticket system comes to an end at the
Canaan toll barrier. The Thruway then interchanges with
New York State Route 22 before crossing into Massachusetts and becoming the Mass Pike.
Cross-Westchester Expressway
Main articles: Cross Westchester Expressway
In 1990, the State Legislature directed the Authority to purchase the Cross-Westchester Expresway (
Interstate 287) from the State, as a toll-free component of the Thruway system for $20 million. The Cross-Westchester begins at I-87/Thruway exit 8 in
Elmsford, where I-287 splits from the Thruway mainline, and travels to the southeast across
Westchester County to
Interstate 95, the New England Thruway, exit 21 in
Rye.
Garden State Parkway Connector
The Garden State Parkway Connector is a 2.40 mile long road that connects the Thruway with the
Garden State Parkway at the
New Jersey state line via interchange 14A. It is the only part of the Thruway system that prohibits commercial vehicles as the parkway prohibits commercial traffic north of exit 105. Although the connector itself is toll free, the Garden State Parkway mainline in
New Jersey is tolled.

Interstate 84
Main articles: Interstate 84 (New York)
Similar to I-287, in 1991, the Authority was directed to assume the cost of operating and maintaining a 70-mile segment of
Interstate 84, an annual expense of approximately $14 million. Only one portion of I-84 in
New York, the
Newburgh-Beacon Bridge connecting
Newburgh and
Beacon, carries a toll. However, the bridge is operated and maintained by the
New York State Bridge Authority, which collects all revenue from tolls on the structure.
As of 2007, there is no direct connection between the Thruway mainline and Interstate 84. Instead, exits from both expressways (I-87/Thruway exit 17 and I-84 exit 7) use
New York State Route 300. The lone interruption along the shared portion of NY 300 is a single
traffic light at the intersection of NY 300 and Stewart Avenue, a local street connecting NY 300 to
New York State Route 17K. Improvements have brought both interchanges individually up to freeway standards, though at a loss to local traffic. The Thruway Authority has a project in the works to build a direct interchange between I-84 and I-87, without compromising local access to either.
[2]
At its October, 2006 meeting, the Authority Board approved an action related to the elimination of the toll barriers at Black Rock and City Line in
Buffalo. After accounting for the cost of toll collection, these barriers were expected to generate approximate $14.1 million. To allow for cessation of toll collections at these locations, the Authority accepted $14.1 million from the State Senate to replace the expected toll revenue for one year. The Board action also authorized providing one-year notice of the return of operational responsibilities of
Interstate 84 to the
NYSDOT as provided for in the Authority's agreement with the same. The return was the only option available to the Board that did not require legislation and was revenue neutral.
[3] The
Grand Island Bridge tolls on I-190 remain intact.
New England Thruway
Main articles: New England Thruway
The New England Thruway (NET) is a 15.01 mile long segment of
Interstate 95 under the operation and maintenance of the Thruway Authority. The Thruway begins at the end of the
Bruckner Expressway at
Pelham Parkway (exit 8) and continues along I-95 to the
Connecticut state line, where I-95 becomes the
Connecticut Turnpike.
Between the
The Bronx and
New Rochelle, the Thruway is toll-free. At New Rochelle, a $1.25 toll is collected by way of a northbound-only toll barrier, the only such structure on the NET.
[4] No toll exists on the entirety of I-95 southbound.
Niagara Thruway
Main articles: Interstate 190 (New York)
The first 21.24 miles of Interstate 190 from I-90 in
Buffalo to
New York State Route 384 in
Niagara Falls is known as the Niagara Thruway and is maintained by the Thruway Authority. North of NY 384, the expressway is named the Niagara Expressway and is maintained by the NYSDOT.
History
A toll
superhighway connecting the major cities of New York State which would become part of a larger nationwide highway network was first proposed in
1949. The following year, the
New York State Legislature passed the
Thruway Authority Act creating the New York State Thruway Authority (NYSTA), an independent
public corporation, which would build and manage the turnpike. The project was to be financed through
toll revenue bonds and self-liquidating by receipt of tolls, rents, concessions, and other income. The act also stipulated NYSTA adopt a hybrid system of tolls, with barrier tolls collected in urban areas, and long-distance tickets issued in rural areas.
The Thruway opened in sections in the early to mid
1950s. The first toll section, between
Lowell and
Rochester, opened on
June 24,
1954. The last section of the 426 mile (681 km) mainline between Buffalo and the Bronx was completed on
August 31,
1956. The total cost was $600 million, financed by the sale of $972 million in bonds. At the time, it was the longest toll road in the world.
The ticket system originally began at the
Spring Valley toll barrier but was later moved to exit 16 to make it possible to build simple toll-free interchanges in the stretch between the two. The toll plaza at Suffern was dismantled along with this change.
[5] The Spring Valley toll barrier remains today as a westbound-only commercial traffic toll.

Example of all-metric signage near Syracuse during the late 1990s.
In
1957, the mainline was extended 70 mi (112 km) west from Buffalo along
Lake Erie to the
Pennsylvania border. From 1957 to
1960, several spurs of the road were built to connect the road to turnpikes in the neighboring states of
Connecticut and
Massachusetts. In
1958, sections of the Thruway were given the current designations as part of the Interstate Highway System.
In
1964, the New York State Legislature officially renamed the Thruway in honor of former governor
Thomas E. Dewey. The official designation is, however, rarely used in reference to the road.
In the late 1970s, the NYSTA experimented with all-metric signage in the
Syracuse area. This experiment included all metric signing for Exits 35 and 36 and a couple of "Speed Limit 88 km/h" signs. Local folklore suggests this stretch of the Thruway was chosen for the experiment because of strong political opposition in the area to the metric conversion plans.
In August
1993, the NYSTA became the first agency to implement the
E-ZPass electronic toll collection system. By December
1996 it was implemented at all toll barriers on the Thruway.
In
1997, the construction
bond used to build the Thruway had been paid off, and all tolls along the Thruway were supposed to be abolished. However, the
New York State Legislature voted to maintain the tolls. This action has engendered regional hostility within the state, particularly from the upstate counties which see the maintenance of the toll as a regional-based tax and that the tolls help maintain the economic disparity between the poor, rural upstate and the rich, urban downstate.
In
2006, the Thruway Authority voted to end tolls on a six mile section of the I-190 portion of the Thruway at the urging of many Buffalo area politicians. Both major candidates in the
2006 gubernatorial election, Democrat and eventual victor
Eliot Spitzer and Republican
John Faso, vowed to eliminate the tolls if elected. Tolls remain on the 496 mile Thruway mainline, as well as on the
North and
South Grand Island Bridges connecting I-190 with the island.
Oh
March 1,
2007, the Thruway Authority announced that wireless internet access (
Wi-Fi) would be available at all service areas along the Thruway.
[6]. Signage for the 27 service areas was updated to reflect this new feature.
