Local-express lanes
The local-express lane (also called collector–distributor lanes within a single interchange) 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. Where highway ramps between express and local/collector lanes cross over one another this is commonly known as braided ramps.[1][2][3][4][5][6]
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.

United States
- California: State Route 180 at the State Route 41 and the State Route 168 interchanges. in Fresno. This interchange is unusual because it also allows traffic to flow between [California State Route 41|State Route 41]] and State Route 168, bypassing the State Route 180 main line, making it almost a double braided ramp.

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.
