An idea I have rattling around in my seemingly-touched head, is to suggest a safe way to re-open travel between these two interconnected cities.
The idea has its nadir in the proposal by WTA prior to I-695’s (and 9/11’s) damage, to operate a joint service with TransLink between Bellingham and Vancouver. Transit Windsor’s TunnelBus service is further inspiration vis-a-vis preclearance.
In this idea, the concept would be to have a pre-clearance site at Fairhaven and at Pacific Central Station. Passengers would be screened and boarded onto a Coast Mountain Bus Company coach, and driven directly to the other terminus, with a 5 minute stop at the Port of Entry, using the priority screening lane. This would allow the route to have a predictable schedule, without having to pad for severe delays.
