Exploration of the origin & history of America's highway-system. I approached this book from the standpoint of a road-trip enthusiast; but for that purpose it didn't meet my needs. The concept is great & some fascinating points are occasionally made; but the author's writing-style is often a hindrance. Initially he buries information under the rubble of overly philosophical, poetic, run-on sentences in the early chapters. Later he turns to an emphasis on politics, national defense & business, as the primary paradigms thru which to view highway development. The subtitle of this book is named "A Celebration of the American Highway," but there's not much celebrating going on. Instead, it seems to offer a cynical expose of self-serving practices by the railroad companies (predecessors of the highways), various other organizations, businesses & government. There is also a tendency towards introducing information as would be done for a history class: w/emphasis on dry, obscure dates & names. I don't need to know every small-town bigshot who put his stamp of approval on a public works project. This reduces what could be an entertaining, enthralling foray, into a quite boring trudge. Much of this is simply tedious minutiae, which I ended up skimming thru. There are chapters which critique roadways thru the lenses of film & literature. His final chapter, "Ends of the Road" is thought-provoking in addressing infrastructure deterioration issues. So much of this book is cerebral; almost intellectual. The author often resorts to haughty vocabulary which would likely be unfamiliar to many readers (ontogeny/phylogeny, apotheosis, phenominologically, etc.. ). I would've enjoyed a more adventuresome, accessible, travel-oriented book, to take the reader on a tour of the major, notable roadway systems in various regions of the country, w/their highlights & landmarks, along w/an entertaining anecdotal history & more of a cultural outlook (instead of delving into matters like the details of franchise establishment in strip-malls). For me, the book was disappointing & I was glad to finish.
