http://www.icbc.com/about-icbc/newsroom/Pages/Southern-Interior.aspxThis ICBC crash map suggests that it is far more dangerous to exit Hwy 5 in Merritt or Kamloops, than it is to cross the pass.
http://globalnews.ca/news/1819213/british-columbias-12-deadliest-highways/Hwy5 is 3rd in this list of 12 worst, but the numbers are significantly different from others in the grouping.
It’s gained a measure of infamy through the Highway Thru Hell TV show, but Jamie Davis, who stars in the series, says the highway itself is structurally sound.
“I can’t criticize the Coquihalla. The main factor is you’re driving over a mountain. It’s not a flat road, it’s a mountainous highway,” he says.
“It requires skill to drive.”
Note that list includes the other two roads out of Hope - up the canyon and through Manning. What would those roads be like if hadn't built the Coke?
