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:
“Let the torpid Monk seek heaven comfortless and alone—GOD speed him! For my own part, I fear, I should never so find the way: let me be wise and religious—but let me be MAN: wherever thy Providence places me, or whatever be the road I take to get to thee—give me some companion in my journey, be it only to remark to, How our shadows lengthen as the sun goes down.”
—Laurence Sterne (1713–1768)
