Unbuilt Highways of San Francisco
A while ago, as more of a challenge to myself, I drew a couple maps of what New York City would look like if Robert Moses had be able to build his Lower-Manhattan Expressway and Mid-Manhattan Expressway. I’ve been interested in unbuilt highways for a while and usually drew out quick sketches on Google Maps. But that isn’t really enough, no. I want a real map of what these cities would look like. Since my Robert Moses maps I’ve gotten great responses, many people asking me to make similar maps for their cities. I was way ahead of them. Originally I had worked on a city-scale map for New York with all the boroughs but I lost track when I had a hard drive failure and lost some of the work.
Now I’m back in the highway groove. Presented here is the first of a series of unbuilt highway Google Maps: San Francisco. The research wasn’t as in depth as with the New York maps only because since so many of these roads never got off the drawing boards there wasn’t much to go on and I had to imagine much of it (most of the off ramps are purely speculative). But the core idea is still there; what would it look like?
Like in many other cities in America in the 1960s, the people of San Francisco began to question the logic of destroying swaths of their city to build intrusive highways which would only serve people who didn’t even live in the city. The Freeway Revolt spread across the nation and stopped many roads high in the air. Most of the maps and plans have been summed up nicely over at San Francisco Transit Oriented Design. Here are some of the historic maps I used:
