A control city is a city or locality posted on a traffic sign indicating forward destinations on a certain route. Most countries post signage known as traffic signs or road signs, at the side of Roads to Signs indicating such cities are usually found at highway junctions to show where the intersecting road goes, or on mileage signs on longer routes.
The determination of major destinations or control cities is important to the quality of service provided by the freeway. Control cities on freeway guide signs are selected by the States and are contained in the "List of Control Cities for Use in Guide Signs on Interstate Highways," published and available from American Association of State and Highway Transportation Officials.
—Federal Highway Administration, Manual on Uniform Traffic Control Devices, 2003 Edition, Chapter 2E
The American Association of State Highway and Transportation Officials (AASHTO) has standardized all control cities used on the Interstate highway system in the United States. The Manual on Uniform Traffic Control Devices (MUTCD is a document issued by the Federal Highway Administration (FHWA of the United States Department of Transportation AASHTO, the American Association of State Highway and Transportation Officials, is a standards setting body which publishes specifications test protocols and The Dwight D Eisenhower National System of Interstate and Defense Highways, commonly called the Interstate Highway System (or simply the Interstate System) The United States of America —commonly referred to as the The published standard is not always followed, either because major destinations have since appeared that were not on the original list, or because of state highway departments' hesitancy to sign destinations in other states. An example is a sign on eastbound Interstate 10 near Palm Springs, California, which, though Phoenix, Arizona is the nearest major forward destination, signs only the small city of Indio, California and "other Desert Cities". Interstate 10 ( I-10) is the southernmost east-west coast-to-coast Interstate highway in the United States. Palm Springs is a desert city in Riverside County, California, approximately 111 miles (177 km east of Los Angeles and 136 miles (225 km northeast of Phoenix (ˈfiːˌnɪks O'odham Skikik, Yavapai Wasinka, Western Apache Fiinigis, Navajo Hoozdo, Indio California, is a US city located in the Coachella Valley of Southern California's Desert region [1]

A control city is not always a major city. For instance, Interstate 76 heading westbound out of Philadelphia, Pennsylvania uses Valley Forge, a historic but minor locality where I-76 joins the Pennsylvania Turnpike. Interstate 76 (abbreviated I-76) is an Interstate Highway in the United States, running 435 miles (700 km from an interchange with Interstate 71 Philadelphia (ˌfɪləˈdɛlfiə The Village of Valley Forge is an unincorporated settlement located on the west side of Valley Forge National Historical Park at the confluence of Valley Creek and The Pennsylvania Turnpike is a toll highway system operated by the Pennsylvania Turnpike Commission in the state of Pennsylvania, United States.
Occasionally, a large city will not be a control city because a larger city is located farther along a highway. For example, highway signs in Maryland on Interstate 95 northbound between the Interstate 395 junction in Baltimore and the Mason-Dixon Line at the Delaware border use New York City as their control city, even though I-95 directly passes through the closer Philadelphia, Pennsylvania (although the branching off of the New Jersey Turnpike from northbound I-95 about 40 miles south of Philadelphia probably accounts for this). Interstate 95 in Maryland is a major highway that runs diagonally from northeast to southwest from Maryland's border with Delaware, to the Woodrow Interstate 395 (abbreviated I-395) is a 2-mile-long spur from Interstate 95 that travels from The Mason–Dixon Line (or "Mason and Dixon's Line" is a Demarcation line between four U The City of New York The New Jersey Turnpike (or simply The Turnpike as it is known to New Jersey residents is a Toll road in New Jersey and is one of the most heavily traveled
Control cities are particularly necessary for highways that do not follow strict linear directions. Ontario's Queen Elizabeth Way, for example, wraps around the western end of Lake Ontario, with segments proceeding both east and west at different points. Ontario (ɒnˈtɛrioʊ is a province located in the central part of Canada, the largest by population and second largest after Quebec The Queen Elizabeth Way (commonly referred to as the QEW, Q, QE, or Queen-E) is a vital 400-Series Freeway in Ontario Lake Ontario is one of the five Great Lakes of North America. Compass directions are not used at all in its central sections, and the control cities of Toronto and (for the opposite direction) Hamilton/Niagara Falls/Fort Erie are the only bearings provided.
