The province is taking a new approach to solve an ongoing traffic problem at one of B.C.’s most popular old groves of trees, which also happens to have a major highway running through it. Starting on Wednesday, the province will begin a series of open houses and collect online feedback about how to solve traffic jams and dangerous pedestrian crossings on Highway 4 at Cathedral Grove in MacMillan Provincial Park outside Port Alberni on Vancouver Island. It’s been been more than 15 years since the province last attempted to fix traffic problems at Cathedral Grove. The previous attempt didn’t solve the safety issues at the popular site, which brings tourists from around the globe. About 500,000 people visit the site each year. …Safety is also still a problem as people often cross the two-lane highway to access trails that showcase the trees, some which are nine metres in diameter and 800 years old.
