[edit] Route description

[edit] Major Deegan Expressway

Main article: Major Deegan Expressway

In New York City I-87 is known as the Major Deegan Expressway (8.4 miles long), which was opened in 1956 before the Interstate highway system was created. The expressway was named for Major William Francis Deegan, of the US Army Corps of Engineers, responsible for the construction of many of the army bases in and around New York during World War I.

[edit] New York State Thruway

Main article: New York State Thruway

The section of highway between the New York City line and the junction with Interstate 90 at Albany is part of the New York State Thruway, for which it was originally constructed in the middle 1950s. The section received its designation as Interstate 87 in 1958.

The Tappan Zee Bridge was created as an extension of the original Thruway route to Suffern, New York. It crosses the Hudson River enabling the route to New York City.

[edit] Adirondack Northway

North of Albany, Interstate 87 is known as the Adirondack Northway or simply the Northway and continues all the way to the United States/Canada border. This controversial segment was built in 1967 to provide a direct route between New York City and Montreal for Expo 67. The same year, Parade Magazine designated the Northway as America's Most Scenic Highway. A long stretch of the Northway through the Adirondack Park is a "dark zone" for cell phone service. A number of recent tragedies have occurred when drivers crashed off the road and could not summon help, prompting calls from local officials to add new wireless towers to address the problem. [1]

The southern portion of the Northway through Colonie and Saratoga County is now a heavily travelled commuter route. Since the highway's construction Saratoga County has become the fastest growing area of the Capital District, and indeed all of upstate New York. [2]

The Northway's southern terminus is at U.S. Route 20 in Guilderland, and the 0.9-mile section of the Northway that is not signed as Interstate 87 (but runs parallel to, and in proximity to, the Thruway/I-87) is maintained by NYSDOT as Reference Route 910F, also known as Fuller Road Alternate.

There is a very short section (0.54 miles long) overlapped with "Free" I-90, between the Thruway and the Northway. Mileposts refer to offramp locations.

[edit] Notes

I-287 connects with its parent in a 19-mile (31 km) long multiplex near the southern end of the highway. It is a partial beltway around New York City. West of the multiplex, it loops around New York to meet the New Jersey Turnpike in Middlesex County, New Jersey. East of the multiplex, I-287 continues as the Cross Westchester Expressway to end at I-95 (the New England Thruway) in Rye, New York, near the Connecticut border. Note that I-287 leaves New York state, while its parent does not.

I-487 (AKA: Hudson River Expressway) was planned to be the I-87 of the east-side of the Hudson. It was planned to run from where I-87 crosses the Hudson at the Tappen Zee Bridge to I-84 in the City of Beacon, NY. It was on the books as a project from the 1930s until the later 1970s. The Croton Expressway along US 9 between Croton-on-Hudson and Peekskill is the only section ever built.

I-587 is less than 2 miles (3.2 km) long. It is unusual in that it has no interchanges along its length: its eastern terminus is at a signalized intersection, while its western terminus is at a roundabout (where it connects to Interstate 87).

I-687 was planned as a bypass around Albany, New York, but it was never built. The interchange that connects Corporate Woods Boulevard to I-90 was intended originally for I-687.

I-787 is a spur route of I-87, from Thruway exit 23 at US 9W, running parallel to the Hudson River through Downtown Albany and leading to Troy. Beyond the Collar City Bridge, the route continues as NY 787 to Cohoes.

Not counting the Canadian border crossing, I-87 is longest Interstate Highway that does not cross any state lines.

Interstate 87 is one of two highways that touch both New York City and the Canadian border in New York, the other being NY 22. US 9 used to, but when I-87 was built to the border, the crossing was rerouted onto it, and 9 now ends at a cul-de-sac just shy of the border. I-95 and US 1 run from New York City to the border in Maine.

The route of part of Interstate 87 is defined as part of Interstate Route Connector 512 and part of Interstate Route 502 in New York Highway Law § 340-a.[3]
