Marine Drive commute
I commuted home via marine drive. Being a small girl, it is super scary, and I was commuting home in the daytime. I have never done it at night.
There is one area from Vancouver Street (I think) where you are re-directed and have to ride up a sketchy path that takes you underneath a bridge (that looks like someone might live under).
Once on Marine drive, you have to navigate the bumpiest ill maintained bike lanes. Glass is EVERYWHERE, not to mention that large trucks and cars are passing you by at highway speeds. Further more, I have never ridden on Marine drive where there were other bike riders with me. It is essentially a ghost town for bikes. That always makes me feel vulnerable, because it means that most of the traffic isn't used to seeing bicycles. I have had several close calls with large trucks cutting in front of me to make right turns.
I don't really have another route recommendation. I was thinking of just crossing over to Interstate at Alberta or Rosa Parks or Lombard and just getting to Delta Park that way. I think it is more bike populated too.
I haven't tried that route, maybe others here can tell you their experiences. But if ever I thought I would die on a bicycle, Marine Drive is where it would be.
