Ididn't go on the most recent Oakland Urban Paths walk earlier this month, but there's a nice write-up of the Rockridge Ramble by OUP founder Paul Rosenbloom.
I did do the test walk with Paul, where we noted the non-matching sidewalk stamps and street signs, at what is now the corner of Romany Road and Golden Gate Avenue. The names stamped in the sidewalk are McAdam St. and Hays Ave., and a nearby contractor stamp is dated 1913. But when were the streets first created? When did they change names?
Examining the great set of historic maps of Oakland at teczno.com, we can learn a few things. McAdam Street is on the 1877 map, and started at "Broadway Street" near where the Safeway is now, and went through land owned by H.P. Livermore. It's not clear how far the street actually went, since on the map the upper part is drawn as a perfectly straight line, which is unlikely given the hills.
Between 1877 and 1912, there was clearly a whole lot of building going on. The 1912 map shows McAdam Street with a different, curvier route, and Hays Avenue, along with a whole lot of other streets that weren't on the earlier map.
The 1936 map shows McAdam Street is now Broadway Terrace, and Hays Avenue is now Golden Gate Avenue. It's possible the labeling as Broadway Terrace is an error, because there's a road in the current location of Broadway Terrace on the map with no label on the nearby section. Finally, the 1950s map shows the present names, Romany Road and Golden Gate Avenue, as do the 1967 map and the current day maps.
