So, Bertha is stuck digging an enormous highway tunnel underneath Seattle. Jeff Wood and I ask the essential question: Does Seattle really need to spend $2.8 billion on a new traffic sewer, when traffic on the Alaskan Way Viaduct has been plummeting?

We also highlight this week’s public conversation about CNU’s big report calling out highways just begging to be demolished. After all, 2013 was the ninth year in a row that Americans drove fewer miles per capita, and some states are beginning to adjust their old assumptions that driving will grow steadily, forever.

We talk about all this and more on the 12th episode of Talking Headways.
