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 collector–distributor lanes within a single interchange. Where highway ramps between express and local/collector lanes cross over one another this is commonly known as braided ramps. One of the longest examples is Ontario Highway 401 between Etobicoke and Pickering in Canada.
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.
This concept is different from Express Toll Lanes.
The following examples include both local-express lanes and collector-distributor lanes.

Other Qualifying Systems (including Collector-Distributer systems)
- California: State Route 180 at the State Route 41 and the State Route 168 interchanges. in Fresno.

Example of cloverleaf interchanges
A cloverleaf interchange may have collector–distributor lanes on a freeway or expressway to handle entering and exiting traffic. Usually, this lane will begin as an entrance-only ramp initially, but it will sometimes become a main lane or possibly an exit-only lane. The purpose of this lane is to facilitate traffic to the freeway exits and from the freeway entrances.
