Interstate 87 (I-87) is a 333.49 mi Interstate Highway located entirely within the U.S. state of New York, and is part of the main highway between New York City and Montreal.
 The highway begins in the Bronx borough of New York City, just north of the Triborough Bridge.
 From there, the route runs northward through the Hudson Valley, the Capital District, and the easternmost part of the North Country to the Canadian border in the Town of Champlain.
 At its north end, I-87 continues into Quebec as Autoroute 15 (A-15).
 I-87 connects with several regionally important roads: I-95 in New York City, New York State Route 17 (NY 17; future I-86) near Harriman, I-84 near Newburgh, and I-90 in Albany.

Interstate 75 (I-75) is a major Interstate Highway in the Great Lakes and Southeastern regions of the United States.
 As with most Interstates that end in a five, it is a major cross-country, north–south route, one of the longest in the U.S., from southern Florida to the northern tip of Michigan.
 It travels from State Road 826 (SR 826, Palmetto Expressway) and SR 924 (Gratigny Parkway) on the Hialeah–Miami Lakes border (northwest of Miami, Florida) to Sault Ste. Marie, Michigan, at the Canadian border.

There are gaps in the Interstate Highway system, where the roadway carrying an Interstate shield does not conform to the standards set by the Federal Highway Administration (FHWA), the body that sets the regulations for the Interstate Highway System.
 For the most part, the Interstate Highway System in the United States is a connected system, with most freeways completed; however, some Interstates still have gaps.
 These gaps can be due to unconnected segments of the same route or from failure of the road to fully conform to Interstate standards by including such things as at-grade crossings, traffic lights, undivided or narrow freeways, or movable bridges (lift bridges and drawbridges).
 This article deals with present-day gaps, as such examples were far more numerous during construction of the Interstate Highway System and the upgrading of existing roads to meet these standards, which did not occur everywhere at the same time.
 Temporary gaps, such as lane closures that reduce traffic to one lane and reduce speed limits, are also excluded.
Interstate 80 (I-80) is a major Interstate Highway in the United States, running from the New York City Metropolitan Area westward to San Francisco, California.
 The New Jersey Department of Transportation also identifies I-80 as the Christopher Columbus Highway.
 I-80 in New Jersey runs 68.54 mi from the Delaware Water Gap Toll Bridge over the Delaware River at the Delaware Water Gap to its eastern terminus at I-95 in Teaneck, Bergen County.
 I-95 continues from the end of I-80 to the George Washington Bridge for access to New York City; access is also provided via the I-280 spur towards the Holland Tunnel and US 46 to Route 3, or I-95, towards the Lincoln Tunnel.
 Throughout New Jersey, I-80 runs parallel to US 46.
 The highway heads through rural areas of Warren and Sussex counties before heading into more suburban surroundings in Morris County.
 As the road continues into Passaic and Bergen counties, it heads into more urban areas.
