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 published standard is not always followed, primarily because major destinations have since appeared that are not on the original list. An example is a sign on Interstate 10 west of Palm Springs, California , which refers to major forward destinations, such as Phoenix, Arizona , simply as "other Desert Cities". {Link without Title} 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 . Occasionally, a large city will not be a control city because a larger city is located further down 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, New York , as their control city, even though I-95 directly passes through the closer Philadelphia, Pennsylvania . This may be due to the so-called "I-95 gap" (the New Jersey Turnpike does not pass through Philadelphia) and New York's Alpha World City status. EXTERNAL LINKS |
