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.

Chuck Marohn, the founder of Strong Towns, has a bone to pick with the field of engineering: Too often, it uses freeway design standards on local streets. Marohn spoke with Andrew as he was promoting his book "Confessions of a Recovering Engineer." He argues engineers need to stop prioritizing speed over safety, and that cities need to stop trying to “solve” congestion.
