In plain English
It is a changed way of getting to the same destination for a limited time. You follow a different path instead of the usual or most direct one when the normal route is unavailable.
In context
Here, "detour" labels the service's temporary alternate route used when its normal route cannot be used.
- Situation
- Using rail, bus, metro, ride, and local-transit tickets and service updates
- What it communicates
- labels the alternate routing arrangement for the service.
Meaning limits
The term by itself does not say how long the change will last or exactly which parts of the usual route are avoided.
Examples
“With the tunnel closed for repairs, the detour sent drivers along the coast road to the same town.”
“While the parade blocks Central Street, the bus follows a detour past the library and back to its usual line near the station.”
