2+1 road is a specific category of three-lane road, consisting of two lanes in one direction and one lane in the other, alternating every few kilometres, and separated usually with a steel cable barrier. Traditional roads of at least 13 metres (43 ft) width can be converted to 2+1 roads and reach near-motorway safety levels at a much lower cost than an actual conversion to motorway or dual carriageway. Denmark and Sweden have been building 2+1 roads since the 1990s.
Famous quotes containing the word road:
“By the road to the contagious hospital
under the surge of the blue
mottled clouds driven from the
northwest—a cold wind.”
—William Carlos Williams (1883–1963)
