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

In road transport, a lane is part of a roadway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, separated by lane markings. On multilane roadways and busier two-lane roads, lanes are designated with road surface markings. Major highways often have two multi-lane roadways separated by a median.
