I rolled the map-roulette wheel, and found a series of highways in

I see 17,943 uses of this value: it's less popular than 5 lanes but more
popular than 6.
What does it mean, if anything?

It may well mean what it says, a one-lane road.  Some rural areas in the
USA still have one-lane roads, with occasional wider spots where one
vehicle can pause to allow a vehicle going the other direction to pass
by.  Given how sparsely-populated some of the northern regions of Canada
are, I would not be surprised to find some one-lane roads, and some
extensive areas with no roads at all.


I just re-read this, and realized that the value was negative 1, not positive 1. Negative 1 probably represents some editor program's way of tagging lanes as "unknown".
