Here’s a map of the 44 which we covered in Two and a Quarter on last week’s Roll Over Easy, with neighborhoods that it passes through, as well as some achievements of Michael O’Shaughnessy himself, including the Twin Peaks and Sunset Tunnels and the cisterns for the Auxiliary Water Supply System, built after the 1906 earthquake. O’Shaughnessy Dam is sadly off the map.

Props to Burrito Justice for the map excellence.
