Tim, this is kind of a terrible idea. Who's going to want to walk seven miles across the bay, with no place to stop. The High Line is great because it's part of a city. The Bay Bridge is a way to get from one city to another.
Let's be happy with the bike lanes on the new bay bridge, and leverage sites like this for achievable neighborhood change.

Impressive work for an undergraduate.
