The local–express lane system is an arrangement of carriageways within a major highway where long distance traffic can use lanes with fewer interchanges compared to local traffic which use 'local' or 'collector' lanes that have access to all interchanges. This can also be called a collector–distributor lane within a single interchange. One of the longest examples is Highway 401 in Toronto, where highway ramps between express and local/collector lanes cross over one another; these are commonly known as braided ramps. This concept is different from express toll lanes.
