Interstate 91 (I-91) is an Interstate Highway in the New England region of the United States.
 It provides the primary north–south thoroughfare in the western part of New England.
 The Interstate's southern end is in New Haven, Connecticut at Interstate 95 and its northern end is at Derby Line, Vermont, a village in the town of Derby, at the Canadian border, where it continues past the Derby Line-Rock Island Border Crossing as Autoroute 55.
 I-91 is the longest of three Interstate highways whose entire route is located within the New England states (the other two being I-89 and I-93), and is also the only primary (two-digit) Interstate Highway in New England to intersect all five of the others that run through the region.
 The largest cities along its route are Springfield, Massachusetts, Hartford, Connecticut, and New Haven, Connecticut, in order from north to south.
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.
 The route is the longest intrastate Interstate Highway in the Interstate Highway System.
 The highway is not contigous with I-87 in North Carolina.
Interstate 73 (I-73) is an Interstate Highway, located within the U.S. state of North Carolina.
 It is part of a longer planned corridor, defined by various federal laws to run from Myrtle Beach, South Carolina, to Sault Ste. Marie, Michigan, but only the part south of West Virginia is under study as of 2012.
 The corridor passes through the states of South Carolina, North Carolina, Virginia, West Virginia, Ohio, and Michigan.
 Ohio and Michigan do not plan to build any part of the highway, as the I-73 corridor in both of these states is already served by existing freeways or 4-lane highways that will eventually be upgraded to freeways.
 West Virginia is building its section, mostly along U.S. Highway 52, as a four-lane divided highway, but not meeting the Interstate Highway standards.
 On the other hand, North Carolina and South Carolina have built sections and Virginia plans to build its part.
 Thus Interstate 73 will, once scheduled projects are completed, run from South Carolina to Roanoke, Virginia, where it will end at Interstate 81.
 Associated with these plans are those for the extension of Interstate 74 from Cincinnati to Myrtle Beach, with several highway overlaps contemplated.
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 25 (I-25) is a part of the Interstate Highway System that runs from Las Cruces, New Mexico, to Buffalo, Wyoming.
 In Wyoming, the Interstate Highway runs 300.530 mi from the Colorado state line near Cheyenne north to its national terminus at I-90 near Buffalo.
 I-25 connects Wyoming's largest city and capital, Cheyenne, with its second largest city, Casper, and the smaller communities of Wheatland, Douglas, and Buffalo.
 The highway also connects those cities with Denver and Billings via I-90.
 I-25 runs concurrently with U.S. Route 87 (US 87) for almost its entire course in Wyoming.
 The highway also has extensive concurrencies with US 20 and US 26 along its east–west segment through the North Platte River valley.
 The Interstate has business loops through Cheyenne, Chugwater, Wheatland, Douglas, Glenrock, Casper, and Buffalo.
Interstate 81 (I-81) is a north–south (physically northeast–southwest) Interstate Highway in the eastern part of the United States.
 Its southern terminus is at I-40 in Dandridge, Tennessee; its northern terminus is on Wellesley Island (near Fishers Landing, New York) at the Canadian border, where the Thousand Islands Bridge connects it to Highway 401, the main Ontario freeway connecting Detroit via Toronto to Montreal.
 The major metropolitan areas that I-81 connects to include Harrisburg in Pennsylvania and Syracuse in New York.
Interstate 990 (I-990) is an auxiliary Interstate Highway located entirely within the town of Amherst in Erie County, New York, in the United States.
 It runs in a roughly north–south direction for 6.43 mi through the southwestern and central parts of Amherst from an interchange with I-290 north of Buffalo to an intersection with New York State Route 263 (NY 263, named Millersport Highway) south of Lockport.
 The highway serves as a connection between Buffalo, the University at Buffalo, and Lockport (via NY 263 and NY 78).
 Like I-590 in nearby Rochester, I-990 does not physically meet I-90, its parent Interstate Highway; instead, the highway makes the connection by way of a "sibling" highway (I-290).
 I-990 is the highest numbered Interstate Highway in the United States.
Interstate 10 (I-10) is the southernmost cross-country interstate highway in the American Interstate Highway System.
 It stretches from the Pacific Ocean at State Route 1 (SR 1) (Pacific Coast Highway) in Santa Monica, California, to I-95 in Jacksonville, Florida.
 The populous cities that I-10 connects to includes (from west to east) Los Angeles, Phoenix, Tucson, El Paso, San Antonio, Houston, Baton Rouge, New Orleans, and Jacksonville.
 This freeway is part of the originally planned Interstate Highway network that was laid out in 1956, and its last section was completed in 1990.
 I-10 is the fourth-longest Interstate Highway in the United States, following I-90, I-80, and I-40.
 About one-third of its length is within the state of Texas, where the freeway spans the state at its widest breadth.
The AA Valley District is a district in Region III of the Virginia High School League.
 As the district's name implies, all the schools are located in the central part of the Shenandoah Valley of Virginia, along Interstate 81.
 Most of the member schools are part of the Harrisonburg and Staunton areas.
The Eisenhower Tunnel, officially the Eisenhower–Edwin C. Johnson Memorial Tunnel, is a dual-bore, four-lane vehicular tunnel approximately 60 mi west of Denver, Colorado, United States.
 The tunnel carries Interstate 70 under the Continental Divide in the Rocky Mountains.
 With a maximum elevation of 11158 ft AMSL, it is one of the highest vehicular tunnels in the world.
 The tunnel is the longest mountain tunnel and highest point on the Interstate Highway System.
 Completed in 1979, it was one of the last major pieces of the Interstate Highway system to be completed.
 The westbound bore is named after Dwight D. Eisenhower, the U.S. President for whom the Interstate system is also named.
 The eastbound bore is named for Edwin C. Johnson, a governor and U.S. Senator who lobbied for an Interstate Highway to be built across Colorado.
