Unfortunatly, there doesn't seem to be any BRB plan in place.
A North Boundary Road Bridge could provide an excellent BRT crossing between Burnaby and North+Vancouver. This would help to relieve pressure on the Iron Bridge.

The same with a South Boundary Roade Bridge with a BRT route between Vancouver and Richmond.
Then another BRT bridge between Richmond and Delta to the ferry terminal. This could help to relieve some of the pressure on the new tunnel, because it wasn't designed to have 2 HOV lanes & no train section.
