"Shank describes in detail the evolution of the state's roads. He starts with Indian trails at the time of the Penn Grant and moves along through pack-horse trails and numerous other types of roads, including military, corduroy, plank, stone-surfaced, brick and concrete. His journey ends with today's limited-access expressways and includes plenty of maps, drawings, photos and human interest stories." [from Abebooks.com]
