Primary Street

These are major roads or boulevards in urban and suburban areas and have large amounts of use (such as Middlefield Rd. in Menlo Park, Park blvd. in Oakland, Constitution Ave. in Washington, DC). In less urban environments they are main thoroughfares in towns that are not US or state highways.
