A Local-express lane system is an arrangement of roadways within a major highway providing one of more roadways for express lanes with a limited number of entrances and exits and also separate roadways for local or collector lanes which provide access to all interchanges. Given the considerable overall width of this design new suburban freeways are often designed with interchanges spaced far enough apart to avoid the need for parallel roadways. Where highway ramps between express and local/collector lanes cross over another the result is known as a basketweave.
