Book excerpt: The true story of the construction of the historic Crozet railroad tunnel—as seen through the eyes of three Irish immigrant families who helped build it. In one of the greatest engineering feats of the time, Claudius Crozet led the completion of Virginia’s Blue Ridge Tunnel in 1858. More than a century and a half later, the tunnel stands as a National Historic Civil Engineering Landmark, but the stories and lives of those who built it are the true lasting triumph. Irish immigrants fleeing the Great Hunger poured into America resolved to find something to call their own. They would persevere through life in overcrowded shanties and years of blasting through rock to see the tunnel to completion. In this intriguing history, Mary E. Lyons follows three Irish families in their struggle to build Crozet’s famed tunnel—and their American dream. Includes photos and illustrations
