MixedThe New York TimesThe discussions of roads and bridges largely deliver on the promise of providing a road map for current policy debates, from big national issues like federal highway funding to ones you’ve probably never thought of, like the lane markings issue. Unfortunately, other parts of the book wander without a clear destination. Through the book, Petroski uses his personal recollections of infrastructure to illustrate current issues in civil engineering. But many of the recollections could have been bypassed.
