On a two-lane highway there was no median. You just had to hope the oncoming drivers all stayed on their side. These would sometimes widen to three lanes on a long and/or steep uphill so the big trucks wouldn't hold everybody up behind them.This is probably one of the few times when Canadians will admit a smidgeon of envy of the US - for their interstate highways. I've driven from one side of Canada to the other on the Trans-Canada Highway (it's our main highway, it sounds like it should be big, right?), and there are substantial portions of it that are not divided. Just two lanes, that is, one in each direction, no median. In the 600 km (375 miles) from Winnipeg to Regina, 400 of those kilometres are undivided and on that whole stretch there are only two "passing lanes" - the aforementioned extra third lane to go around trucks. In fact, most of the Trans-Canada is not divided, now that I think about it. If you're behind a truck you just have to gun it and hope that you could see far enough away not to hit anyone! And driving through the Rockies is nerve-wracking for a flatlander like myself...
