Connector (road)

A connector is a highway or freeway road that connects to another highway or freeway. It can be part of an interchange such as the MacArthur Maze or a longer roadway such as the 13 mi (20 km) Interstate 635 (Kansas-Missouri).

A connector route is a type of special route or supplemental route in the United States that serves as a connector, connecting one route to a more prominent route. Connector routes are found among the United States Numbered Highways and among some state route systems like Michigan and Nebraska.

Connector routes can also be designated as a routing between two numbered highways. For example, Connector M-44 runs along Plainfield Avenue between Interstate 96 and M-44 north of Grand Rapids, Michigan.
