Book excerpt: Roads are rarely given a second thought yet are indispensable to life. Admittedly, a book dedicated to roadways sounds a bit dry. But behind every double-diamond interchange, every pork chop island, and every type of asphalt is a fascinating history of the traveling public. This book reveals the hidden history of building the Silver State's highways since 1917. The next time you take a road trip across Nevada on the Lincoln Highway (US 50) or the Victory Highway (US 40) or follow a rutted road to a once-booming ghost town think of the ingenious and industrious men and women, surveyors, engineers, chemists, and yes, even the teams of mules that built the roads we still travel today.
