BC Transit wants to hand the Fraser Valley Express three more buses next year—so long as the province provides enough funding—and buses—to go around.

The Fraser Valley Express runs between Chilliwack and Lougheed Town Centre with stops in Abbotsford and Langley. It has been a hit since its launch in 2015, but its popularity has posed recent challenges, with some buses reaching capacity at Abbotsford and leaving riders waiting for the next vehicle.

That problem was so severe that, earlier this year, BC Transit pulled money from its internal budget in order to add two more buses to the route.

Now, the transit agency and the Fraser Valley Regional District have put together a plan to further boost BC’s most-popular inter-regional bus service. They also want to create a new regional route between Agassiz and Mission. But there are several potential roadblocks that could stall the buses before they ever hit the road.
