> The standard English term for a bridge that is only wide enough for one vehicle to pass through at a time is a "one-lane bridge". In the same way, a roadway only wide enough for one vehicle at a time is a "one-lane road". The bridge or road is visibly only one lane wide; painting lane markings on it to point out its narrowness would be redundant.
Back to my initial case in Madagascar. I'm first talking about major
roads where two vehicles (incl. trucks) can cross without lowering there
speeds. Although there is not central line (except in curves), there is
virtually two lanes.
I understand that there is some redundancy between lanes=* and width=*,
especially for for roads without painted lanes. But I like lanes=* for a
rough description of the gauge.
About the bridge, there is usually a road sign announcing the narrowing:
It may be completed with a stop a each end of the narrow passage and
sometime with a bump. Without bump, you may cross the bridge at full
speed if no other vehicle is arriving in front. Otherwise, first
engaged, first served ;-) So lanes=1 corresponds to the bridge, although
width=* would be better but hard to determine.
