With nearly 375 affected bus stops on 18 impacted routes and several rider fare adjustments, C-Tran is about to make the largest change to its services in a decade — and it’s all happening in the first week of September.“Mak(ing) transit really more accessible to everyone, that’s the reason why we do this,” said C-Tran Spokeswoman Christine Selk of the service changes that take effect Sunday.The majority of route changes are adjustments to existing routes. Perhaps the greatest change comes to Portland-bound commuters. Route 44 is being discontinued completely. Route 4 will no longer serve Delta Park or Jantzen Beach. Instead riders will have to get off in downtown Vancouver and transfer onto the new Route 60.“Making another connection will increase commute times from Delta Park. However, it’s also the nature of the route itself,” Selk said in an email. “When you have a route that goes off-schedule due to traffic and bridge lifts, it can be a challenge to keep all those buses on time.”Part of those changes is to prepare for The Vine, Vancouver’s bus rapid transit system which is supposed to come online at the end of the year.
