Interstate 80 in Utah: Interstate 80 (I-80) is a part of the Interstate Highway System that runs from San Francisco, California, to Teaneck, New Jersey.  The portion of the highway in the U.S. state of Utah is 196.35 mi , through the northern part of the state.  From west to east, I-80 crosses the state line from Nevada in Tooele County and traverses the Bonneville Salt Flatswhich are a part of the larger Great Salt Lake Desert.  It continues alongside the Wendover Cut-offthe corridor of the former Victory HighwayU.S. Route 40 (US-40) and the Western Pacific Railroad Feather River Route.  After passing the Oquirrh Mountains, I-80 enters the Salt Lake Valley and Salt Lake County.  A short portion of the freeway is concurrent with I-15 through Downtown Salt Lake City.  At the Spaghetti Bowl, I-80 turns east again into the mouth of Parley's Canyon and Summit County, travels through the mountain range and intersects the eastern end of I-84 near Echo Reservoir before turning northeast towards the Wyoming border near Evanston.  I-80 was built along the corridor of the Lincoln Highway and the Mormon Trail through the Wasatch Range.  The easternmost section also follows the historical routes of the First Transcontinental Railroad and US-30S.

Spaghetti Bowl (Las Vegas): The Spaghetti Bowl is the colloquial name for a freeway interchange near downtown Las Vegas, Nevada.

Interstate 84 in Utah: Interstate 84 (I-84) is a part of the Interstate Highway System that links Portland, Oregon to I-80 near Echo, Utah.  The 119.77 mi segment in the U.S. state of Utah is the shortest of any of the three states the western portion of the Interstate Highway passes through, and contains the eastern terminus of the highway.  I-84 enters Box Elder County near Snowville before becoming concurrent with I-15 in Tremonton.  The concurrent highways travel south through Brigham City and Ogden and separate near the Ogden-Hinckley Airport.  Turing east along the Davis County border, I-84 intersects U.S. Route 89 (US-89) and enters Weber Canyon as well as Morgan County.  While in Morgan County, I-84 passes the Devil's Gate-Weber Hydroelectric Power Plant and Devil's Slide rock formation.  Past Morgan, the highway crosses into Summit County, past the Thousand Mile Tree before reaching its eastern terminus at I-80 near Echo.

1962 Utah state route renumbering: Coinciding with the designation of several routes in the Interstate Highway System through Utah, the Utah State Legislature made several changes to the Utah State Route system.  The bulk of these changes were not visible to the public, but were to unsigned legislative designations only.  The primary effect was designating route numbers 1 through 5 for future corridors of the Interstate Highways in Utah.  There were also changes made to a few unsigned highways serving state parks and institutions.  Several other routes were truncated or re-assigned or split into multiple designations to allow the Interstate Highway corridors to have a single route number assigned.  As very little of the Interstate Highway System had been constructed in Utah by 1962, these changes were primarily to support future construction.  There were a number of cases where the legislative change enacted in 1962 would not be built and signed until years later.  Few of the changes made in 1962 are still valid today.  As construction of the Interstate Highway system proceeded, additional changes were made.  The legislature made a larger change in route designations in 1977, eliminating unsigned legislative and concurrences in the process.

Interstate 15 in Idaho: Interstate 15 (I-15) is a part of the Interstate Highway System that runs from San Diego, California, to Sweetgrass, Montana.

List of Interstate Highways in New York: There are 32 Interstate Highways—9 main routes and 23 auxiliary routes—that exist entirely or partially in the U.S. state of New York.  In New York, Interstate Highways are mostly maintained by the New York State Department of Transportation (NYSDOT), with some exceptions.  Unlike in some other states, Interstate Highways in New York are not directly referenced by NYSDOT with their number; instead, the letter "I" is suffixed to the number of the route on reference markers and in internal documents.  On the surface, there appears to be numerical duplication between several Interstate Highways and state routes—such as I-86 (I-86) and NY 86—but the "I" suffix that is appended to Interstate Highway numbers allows the Interstate Highway and state route to co-exist ("86I" versus "86", respectively).

Interstate 15 in Nevada: Interstate 15 (I-15) is an Interstate Highway in the U.S. state of Nevada that begins in Primm, continues through Las Vegas and it crosses the border with Arizona in Mesquite.  The freeway runs entirely in Clark County.  Many motorists use I-15 to visit Las Vegas, as it is the only primary Interstate Highway in the city.  The highway was built along the corridor of the older U.S. Route 91 (US 91) and Arrowhead Trail, eventually replacing both of these designations.
