I like the idea of just tunneling the whole length to avoid and protect the sensitive surface. Just like the Chunnel: A rail link could be used to maximize throughput for the tunnel size. Cars and trucks could travel on shuttles on the rail link. Maybe 2-3 times the distance of the Chunnel, but doable for connecting two continents.

That approach would be easier to physically secure against threats (people and pests) compared to a surface road. The article sites a lack of bedrock to use for bridges, that could be a blocker for a tunnel. Though I'm sure there's rock down there somewhere if you dig deep enough. I'd like to see zip lines. The longest and highest capacity ever built. Carry cars and freight. It'd be an engineering stepping stone towards the tether for a space elevator.
