As most people are focusing on the construction of the new Bay Bridge—slated to be finished by 2013—others are thinking of ways to reuse parts of the old one. Inspired by New York's High Line, an old railway turned into an urban park, Bay Area architect Ronald Rael is proposing to save the eastern span of the Bay Bridge from demolition and reusing it for a project he calls the Bay Line, a site that could include parks, swimming pools, and housing. Although it's only an idea, the Bay Line project has started a wider debate on how cities around the world could reuse historical structures like the Bay Bridge.
