Bill,
I've driven the Coquihalla 3 or 4 times in the last 3 years. If I recall correctly, the toll is $10 Cdn. And I'm sure they'll take our $.
It is a cool drive, great scenery, especially in winter. I once did it in my Toyota 4wd, a light little wanna be twuck, and not real stable at high speed in 2 wheel drive. I was in a hurry to meet a chairlift ride time deadline at Sun Peaks for a moonlight dinner, paid for by the ski area, and I made the trip from Shoreline in record time...for a puny 4 banger that barely makes 40 mph on the many big hills. But 80-90 on the downhill grades made for some white knuckle time..with the flakes a flyin'.
