On the other hand, there are also instances where intrastate control cities have been left out so that long-distance focal points could be added. There are also instances where the name of another state has prevailed over the official control city, e.g. the signs in Boston heading to the state of Maine ("All Maine Points" appears twice on northbound I-95 just south of Portsmouth, NH.). On the U.S. federal list, control cities have often been selected by virtue of being located close to an intersection of two US-interstates. This has resulted in a number of very minor localities having control city status. Some examples:  However, in many other instances, the next major city near or along the route is used as a control city, often skipping over minor localities where two US-interstates meet. For instance:    Some beltways or spurs which run through multiple states have different rules on control cities in each state. One instance is Interstate 435, the beltway in the Kansas City Metropolitan Area. Signs for I-435 in Kansas do not have control cities listed, while in Missouri, one of five control cities is listed, depending upon direction and location: Des Moines, St. Joseph, St. Louis, Topeka and Wichita. Under the Manual on Uniform Traffic Control Devices, control cities must appear on the route signs:    Since the towns on post-interchange distance signs are listed in ascending order of distance, the control city of routes in the United States is typically the most distant locality on the signs of a particular road. Freeways in Australia, whilst not using the term 'Control City', operate on much the same system as in the United States and Europe. Directional markers are not used, instead the next large towns or cities which are likely to be the destination, or known waypoints for motorists, are used. There is no absolute threshold of community size or distance away, or absolute necessity that it has to be a city per se in order to be selected. Even some highways will terminate several miles before the so-called "control city" and "borrow" another route to continue toward there, even if a north–south highway has to externalize its control city to an east–west highway. For instance, Interstate 75 in Michigan uses the Mackinac Bridge as a "control city", and even U.S. Route 127 in Michigan does it as far south as Mt. Pleasant. Another idiosyncrasy with control cities is there is no absolute rule that the city has to be reached before the control city changes, for instance Interstate 94 in Michigan uses Chicago as a control city as far as the Metro Detroit area, whereas some in-between cities such as Jackson are used within of there.
