- Definition
- An indication that a road serves as a section of a road interchange, providing traffic access from one through road to another, but does not itself carry through traffic.
- Description
- Through roads normally are located on separate vertical levels, thus affording uninterrupted traffic flow, with at least one road being supported by a bridge and the other proceeding through an underpass. In the case of a rotary interchange on a single level there is no uninterrupted through route, therefore all traffic flows pass along road interchange ramps.
