Part ll of Cris Subrisi’s story of San Francisco’s Central Subway treats the problems of constructing the stations (which are buildings in themselves) underground without disrupting street activity. His illustrated account of the history of the cut-and-cover approach to underground construction begins with a tunnel under the Euphrates River in ancient Roman times and ends with San Francisco’s Union Square Market Street station.
