Freeway Exit
Freeways are not free. We pay for them in all kinds of ways — with our tax dollars, our time, our environment and our health. While freeways have enabled huge amounts of economic growth, they've also caused displacement and division. Learn the forgotten history of our urban freeway network, and how decades after that network was finished, some communities are still working to heal the wounds that freeways left behind. As climate change threatens to wreak havoc on our cities, freeways are not just a part of the problem. They can also be part of the solution.

Our methods for measuring the economic impact of freeways are rooted in 1950s logic. A new report, "Divided by Design" from Smart Growth America, uncovers just how much they leave out. Co-author Beth Osborne says we tend to overestimate how much time and money we'll save on freeways. And we ignore the ways in which freeways can sometimes make trips longer. ...

A devastating earthquake forces San Francisco to consider the radical notion of tearing a freeway down. The results are wildly successful: The Embarcadero Freeway is replaced with a transit and pedestrian-friendly boulevard. The Central Freeway's removal revitalizes a neighborhood and improves safety.
