Definitions for dual carriageway
This page provides all possible meanings and translations of the word dual carriageway
divided highway, dual carriageway(noun)
a highway divided down the middle by a barrier that separates traffic going in different directions
"in Britain they call a divided highway a dual carriageway"
A road in which the two directions of traffic are separated by a central barrier or strip of land, known as a central reservation or median.
A dual carriageway is a class of highway with two carriageways for traffic travelling in opposite directions separated by a central reservation. Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways. A road without a central reservation is a single carriageway regardless of the number of lanes. Dual carriageways have improved road traffic safety over single carriageways and typically have higher speed limits as a result. In some places, express lanes and local/collector lanes are used within a local-express-lane system to provide more capacity and to smooth traffic flows for longer-distance travel.
