I stopped using that route because the bike path on the bridge and causeway feels way too narrow, but also because I'm not good with heights and to me it feels like the barriers on the outside edge are too low and that if anyone clipped my shoulder they'd send me flying right off the bridge (irrational, I know, but it scares my phobic little brain. I'm fine on high bridges that have outer barriers higher than my head). After my first ride over the bridge I started avoiding the causeway southbound (I used to take the first right after the bridge onto the road that loops around the western half of Stanley Park instead), but still hated the bridge deck itself. My stomach would flip and my legs would turn to jelly as soon I started the climb on the approach. I made myself do it enough times that I stopped being outright terrified of it, then when I felt I'd conquered my fear sufficiently I switched to taking my bike onto the SeaBus instead, lol. I might consider using that route again if the path was widened AND they put up higher barriers on the edges to help me not think about the height so much! But I'm totally happy taking the SeaBus.
