Freewaytopia: How Freeways Shaped Los Angeles explores how social, economic, political, and cultural demands created the web of expressways whose very form-futuristic, majestic, and progressive-perfectly exemplifies the City of Angels.

From the Arroyo Seco, which began construction during the Great Depression, to the Simi Valley and Century Freeways, which were completed in 1993, author Paul Haddad provides an entertaining and engaging history of the 527 miles of road that comprise the Los Angeles freeway system.

Each of Los Angeles's twelve freeways receives its own chapter, and these are supplemented by "Off-Ramps"-sidebars that dish out pithy factoids about Botts' Dots, SigAlerts, and all matter of freeway lexicon, such as why Southern Californians are the only people in the country who place the word "the" in front of their interstates, as in "the 5," or "the 101."

Freewaytopia also explores those routes that never saw the light of day. Imagine superhighways burrowing through Laurel Canyon, tunneling under the Hollywood Sign, or spanning the waters of Santa Monica Bay. With a few more legislative strokes of the pen, you wouldn't have to imagine them-they'd already exist.

Haddad notably gives voice to those individuals whose lives were inextricably connected-for better or worse-to the city's freeways: The hundreds of thousands of mostly minority and lower-class residents who protested against their displacement as a result of eminent domain. Women engineers who excelled in a man's field. Elected officials who helped further freeways . . . or stop them dead in their tracks. And he pays tribute to the corps of civic and state highway employees whose collective vision, expertise, and dedication created not just the most famous freeway network in the world, but feats of engineering that, at their best, achieve architectural poetry.

Finally, let's not forget the beauty queens-no freeway in Los Angeles ever opened without their royal presence.
