in which Interstate 64 goes east toward Charleston. Another example is Interstate 65, as Chicago, Illinois is used as a control city north of Indianapolis, Indiana, but I-65 terminates at Interstate 90 and the Indiana Toll Road in Gary, Indiana, 26 miles southeast of Downtown Chicago, and I-90 goes northwest into Chicago via the Toll Road, Chicago Skyway Bridge and Dan Ryan Expressway. In the case of concurrencies, another control city from the overlapping highway can take over, and sometimes two locations are used together. Other idiosyncrasies involve forcing a control city to be within the state or province. For instance Ontario highway 401 uses Kingston, Ontario as a control city, even though Montreal in the neighboring province is bigger, though it is not too far from Kingston either. This tactic, however, forces cities within the province to represent the majority of the length so as to not have much distance of remainder to the control city in the neighboring province.
