The Thousand Islands Parkway (TIP) is a scenic parkway in the Canadian province of Ontario, which extends easterly from an interchange with Highway 401 in Gananoque for approximately 40 kilometres (25 mi) to rejoin Highway 401 in the community of Butternut Bay, in Elizabethtown-Kitley, west of Brockville.


The parkway follows the north shore of the St. Lawrence River, and was formerly designated Highway 2S (for Scenic). It was constructed as a primary freeway segment in the Toronto–Montréal corridor during the late 1930s. The Thousand Islands Bridge opened in 1938, during the parkway's construction. The parkway was signed as part of Ontario Highway 401 when the 400-series highway system was established in 1952, losing this designation in 1968 once the current Highway 401 alignment (through Lansdowne, Ontario) was completed further north.

Evidence of its former use can be seen today in the wide right-of-way; the unused westbound lanes now serve as a bicycle trail and twin bridges span two locations along the parkway.

Thousand Island Parkway heading eastbound over Landon Bay

The Thousand Islands Parkway begins at a split with Highway 401 on the outskirts of Gananoque. There is no access from westbound Highway 401 to the parkway nor from westbound on the parkway to eastbound Highway 401. However, immediately east of the split, both highways interchange with the sole remaining portion of Highway 2 under provincial jurisdiction. East of this point the three diverge into the rugged terrain of the Frontenac Arch, a protrusion of the Canadian Shield southward into New York state. In this area, the soil is underlain by layers of Paleozoic limestone and a granite bedrock. The granite often extends above the ground surface as large rock outcroppings. Both layers are prominent in the Jones Creek ravine. [3]

It interchanges at its midpoint with Highway 137, the Ontario approach to the Thousand Islands Bridge which continues as Interstate 81 south of the Canada–United States border. The parkway continues northeast, serving the riverside communities of Darlingside, Rockport, Narrows, La Rue Mills and Mallorytown Landing. At Butternut Bay, the Thousand Islands Parkway merges into the eastbound lanes of Highway 401 and a left-hand exit provides access to the parkway from westbound Highway 401. [3]

A recreational trail to the north runs parallel to the parkway for most of its length.The Thousands Islands Parkway follows what was the original alignment for Highway 401. However, because of the residential properties and the scenic nature of the route, a new inland route was constructed through the mid-1960s and the recreational trail follows the right-of-way for planned westbound lanes which were never completed.


While today only a two-lane road, it was a divided and paved four lane roadway in the early 1940s. [4] [5] [6]

The St. Lawrence River Road was given the designation of Highway 2S in 1947. This designation remained in place for several years, until the entire route was renumbered as Highway 401 by the end of 1952. Initially, the parkway was intended as the route of Highway 401 between Gananoque and Brockville. However, when the Department of Highways (DHO) encountered severe local resistance, it was instead decided that a new bypass should be built further inland. This bypass opened on October 11, 1968, at which point the entire parkway once again became Highway 2S.

This designation would also only last for just under two years. On September 8, 1970, the DHO transferred the jurisdiction over the parkway to the St. Lawrence Parks Commission; [2] it was subsequently renamed as the Thousand Islands Parkway.

Route 124 is a state highway in the northern part of New Jersey in the United States that is 14.74 mi (23.72 km) long. It is the eastern section of what used to be Route 24 before that road was realigned to its current freeway alignment. The western end is at an intersection with U.S. Route 202 (US 202) and County Route 510 (CR 510) in Morristown, Morris County; the eastern end continues as CR 603 on Springfield Avenue at the border between Maplewood and Irvington in Essex County. The route runs through suburban areas of Morris County, passing through Madison and Chatham. It interchanges with Route 24 on the border of Millburn, Essex County and Summit, Union County and serves as a frontage road for that route. Upon splitting from Route 24, Route 124 continues east through Springfield Township, Union Township, and Maplewood to its eastern terminus.

Ontario Highway 401 Highway in Ontario

King's Highway 401, commonly referred to as Highway 401 and also known by its official name as the Macdonald–Cartier Freeway or colloquially referred to as the four-oh-one, is a controlled-access 400-series highway in the Canadian province of Ontario. It stretches 828 kilometres (514 mi) from Windsor in the west to the Ontario–Quebec border in the east. The part of Highway 401 that passes through Toronto is North America's busiest highway, and one of the widest. Together with Quebec Autoroute 20, it forms the road transportation backbone of the Quebec City–Windsor Corridor, along which over half of Canada's population resides. It is also a Core Route in the National Highway System of Canada. The route is maintained by the Ministry of Transportation of Ontario (MTO) and patrolled by the Ontario Provincial Police. The speed limit is 100 km/h (62 mph) throughout its length, with the only exceptions the posted 80 km/h (50 mph) limit westbound in Windsor and in most construction zones.

The Conestoga Parkway is a freeway in the Regional Municipality of Waterloo, in the Canadian province of Ontario. It runs northeast/southwest through the cities of Kitchener and Waterloo, and is connected to Highway 401 via the Highway 8 Freeport Diversion and King Street East. The name "Conestoga Parkway" is not a formal designation, but rather a local name applied to the divided expressway portions of Highway 7, Highway 8 and Highway 85 through Kitchener and Waterloo. When the parkway opened in the late 1960s there were a few large green and white signs reading "Conestoga Parkway" with a picture of a Conestoga wagon on them located along the parkway. By the 1990s after several sections of the parkway had undergone reconstruction and expansion, these signs had been removed but many maps still show this as the name of the freeway. Most residents of Kitchener and Waterloo refer to the parkway as "The Expressway". By contrast, the portion of Highway 8 which departs from the parkway at King Street East in Kitchener and runs to Highway 401 is often referred to as the Freeport Diversion, "Highway 8 Expressway" or "King Street Bypass" by local residents.

Ontario Highway 115 Highway in Ontario

King's Highway 115, commonly referred to as Highway 115 is a provincially maintained highway in the Canadian province of Ontario that connects Peterborough with Toronto via Highway 401. The highway begins at a junction with Highway 401 southwest of Newcastle and ends at an at-grade intersection with Highway 7 east of Peterborough.

The Belt Parkway is the name given to a series of connected limited-access highways that form a belt-like circle around the New York City boroughs of Brooklyn and Queens. The Belt Parkway comprises three of the four parkways in what is known as the Belt System: the Shore Parkway, the Southern Parkway, and the Laurelton Parkway. The three parkways in the Belt Parkway are a combined 25.29 miles (40.70 km) in length. The Cross Island Parkway makes up the fourth parkway in the system, but is signed separately.

Ontario Highway 427 Highway in Ontario

King's Highway 427, also known as Highway 427 and colloquially as the 427, is a 400-series highway in the Canadian province of Ontario that connects the Queen Elizabeth Way (QEW) and Gardiner Expressway in Toronto to Highway 401 and with York Regional Road 7 further north in the city of Vaughan. It is Ontario's second busiest freeway by volume and the third busiest in North America, behind Highway 401 and Interstate 405 in California. Like Highway 401, a portion of the route is divided into a collector-express system with twelve to fourteen continuous lanes. Notable about Highway 427 are its several multi-level interchanges; the junctions with the QEW/Gardiner Expressway and Highway 401 are two of the largest interchanges in Ontario and were constructed between 1967 and 1971, while the interchanges with Highway 409 and Highway 407 were completed in 1992 and 1995, respectively.

The E. C. Row Expressway is a municipal expressway in the city of Windsor, Ontario, Canada. It divides the city in half as it crosses it between the Ojibway Parkway in the west and Banwell Road in the east, a distance of 15.4 kilometres (9.6 mi). It was built between 1971 and 1983, reaching completion across the city on June 9, 1983. It was part of Highway 2 and Highway 18 until the province transferred ownership and responsibility for the route to the City of Windsor on April 1, 1997. In 2015, the westernmost 3 kilometres (1.9 mi) was significantly upgraded as part of the Highway 401 extension project. The freeway is named after Edward Charles Row, the president of Chrysler Canada between 1951 and 1956.

Ontario Highway 2 Highway in Ontario

King's Highway 2, commonly referred to as Highway 2, is the lowest-numbered provincially maintained highway in the Canadian province of Ontario and was originally part of a series of identically numbered highways in multiple provinces which together joined Windsor, Ontario to Halifax, Nova Scotia.

Ontario Highway 403 Highway in Ontario

King's Highway 403, or simply Highway 403, is a 400-series highway in the Canadian province of Ontario that travels between Woodstock and Mississauga, branching off from and reuniting with Highway 401 at both ends and travelling south of it through Hamilton and Mississauga. It is concurrent with the Queen Elizabeth Way (QEW) for 22 km (14 mi) from Burlington to Oakville. Although the Highway 403 designation was first applied in 1963 to a short stub of freeway branching off the QEW, the entire route was not completed until August 15, 1997, when the section from Brantford to the then-still independent Town of Ancaster was opened to traffic. The section of Highway 403 between Woodstock and Burlington was formally dedicated as the Alexander Graham Bell Parkway on April 27, 2016.

Ontario Highway 405 Highway in Ontario

King's Highway 405, also known as Highway 405 and the General Brock Parkway, is a 400-Series Highway in the Canadian province of Ontario connecting the Queen Elizabeth Way (QEW) near St. Catharines with the Lewiston–Queenston Bridge in the village of Queenston. It then crosses the Niagara River, where it encounters the international border with the United States and continues into New York as Interstate 190 (I-190).

Ontario Highway 402 Highway in Ontario

King's Highway 402, commonly referred to as Highway 402 and historically as the Blue Water Bridge Approach, is a freeway in the Canadian province of Ontario that connects the Blue Water Bridge international crossing near Sarnia to Highway 401 in London. It is one of multiple trade links between Ontario and the Midwestern United States. Its 400-series number denotes a King's Highway with controlled access. It is four lanes for much of its length, though the approach to the Blue Water Bridge is six lanes.

New York State Route 878 (NY 878) is a state highway on Long Island, in the southern portion of the U.S. state of New York. The route exists in two sections, which both form the Nassau Expressway. NY 878's western terminus is the Belt Parkway and Conduit Avenue (NY 27) in Ozone Park, within southern Queens. Its southern terminus is immediately before the Village of Atlantic Beach, at the Atlantic Beach Bridge in Lawrence, within southwestern Nassau County. NY 878 is discontinuous between Farmers Boulevard in Queens and the town of Inwood in Nassau County. The two sections are connected to each other by Rockaway Boulevard and Rockaway Turnpike.

New York State Route 27 (NY 27) is a 120.58-mile (194.05 km) long state highway that runs east-west from Interstate 278 (I-278) in the New York City borough of Brooklyn to Montauk Point State Park on Long Island, New York. Its two most prominent components are Sunrise Highway and Montauk Highway, the latter of which includes the Montauk Point State Parkway. NY 27 acts as the primary east-west highway on southern Long Island east of the interchange with the Heckscher State Parkway in Islip Terrace. The entire route in Suffolk, Nassau, and Queens counties were designated by the New York State Senate as the POW/MIA Memorial Highway. The highway gives access to every town on the South Shore. NY 27 is the easternmost state route in the state of New York.

King's Highway 137, commonly referred to as Highway 137, is a provincially maintained highway in the Canadian province of Ontario that serves to connect the northern end of Interstate 81 in New York with Highway 401, via the Canadian span of the Thousand Islands Bridge. While this road connected to the international bridge when it opened in August 1938, it was not designated as a King's Highway until 1965. Highway 137 passes through a portion of the Canadian Shield, a geographic feature which aided construction of the three Canadian spans of the Thousand Islands Bridge. These bridges, all of different designs, travel 538 m (1,765 ft) across the Saint Lawrence River. Highway 137 is 4.3 km (2.7 mi) in length and is located entirely within the United Counties of Leeds and Grenville.

King's Highway 8, commonly referred to as Highway 8, is a provincially maintained highway in the Canadian province of Ontario. At a length of 159.7 kilometres (99.2 mi), the route is significantly shorter than when it travelled beyond Hamilton to Niagara Falls. However, the Queen Elizabeth Way (QEW) replaced the role of Highway 8 between those two cities, and that portion of the highway was subsequently transferred from provincial to local jurisdiction. Today the highway connects Hamilton and Cambridge, thereafter continuing through Southwestern Ontario to the community of Goderich on the shores of Lake Huron. The freeway segment of Highway 8 is known as the Freeport Diversion, King Street Bypass, or Highway 8 Expressway, with a short portion being internally designated by the province as Highway 7187. Highway 8 is multiplexed with Highway 7 including a portion of the Conestoga Parkway.

Ontario Highway 502

Secondary Highway 502, commonly referred to as Highway 502, is a provincially maintained secondary highway in the Canadian province of Ontario. The highway is 151.7 kilometres (94.3 mi) long, connecting Highway 11 east of Fort Frances with Highway 17 in Dryden, via Highway 594. It also carries the Great River Road designation.

King's Highway 40, commonly referred to as Highway 40, is a provincially maintained highway in the southwestern portion of the Canadian province of Ontario. The route links Chatham and Sarnia via Wallaceburg, following close to the St. Clair River. The southern terminus is at Highway 401 south of Chatham, while the northern terminus is at Highway 402 in Sarnia.

Delaware Route 4 (DE 4) is a state highway in New Castle County, Delaware. The route runs from DE 279 and DE 896 in Newark east to DE 48 in downtown Wilmington. The route passes through suburban areas in northern New Castle County between Newark and Wilmington, intersecting DE 72 in the eastern part of Newark, DE 273 in Ogletown, DE 58 in Christiana, DE 7 in Stanton, DE 141 in Newport, DE 62 and DE 100 between Newport and Wilmington, and Interstate 95 (I-95)/U.S. Route 202 (US 202) in Wilmington. DE 4 is a four-lane road for much of its length.

King's Highway 32, commonly referred to as Highway 32, was a provincially maintained highway in the Canadian province of Ontario. The 19.6-kilometre (12.2 mi)-long route connected Highway 2 in Gananoque with Highway 15 east of Seeleys Bay, providing a quick alternative route between the two highways. It also featured an interchange with Highway 401. Highway 32 was assumed in 1929, and generally remained unchanged throughout its existence until 1998, when it was decommissioned and transferred to the United Counties of Leeds and Grenville. It was subsequently redesignated as Leeds and Grenville County Road 32.

King's Highway 76, commonly referred to as Highway 76, was a provincially maintained highway in the Canadian province of Ontario. The route began at Highway 3 in Eagle and progressed north through the community of West Lorne, encountering Highway 401 immediately before terminating southwest of Glencoe at Longwoods Road. Today the route it followed is known as Elgin County Road 76 and Middlesex County Road 76.
