A major collector roadway distributes traffic between residential streets, collectors, and arterial streets. The major collector's purpose is primarily to promote free traffic flow. Thus, direct access for adjoining lots should be limited where possible. Major collectors should not be used for on-street parking and may provide linkages to adjoining developments to improve vehicle circulation. A major collector is designed to carry more traffic by removing the single turn lane on a minor collector in favor of two (2) dedicated lanes running in each direction. Village streets serving as state routes may have additional requirements per ODOT standards.
