I thought this was well-researched and fairly well-written, although it's beyond obvious that many of the chapters should be their own books. Strand does a decent job of intermingling the stories of highway violence and serial killers with the growth of the interstate system without straying into overblown descriptions of said violence. Each chapter touches on a topic that wider-reaching than one could address in a single chapter, and it's too her credit that she is both focused enough to tell most of each story, while not losing sight of the larger cultural picture.
