Kilo, my changes were based on the survey that I conducted. 

Thoreau Path was a giant pedestrian street, could probably even be designated as a service road since there was a service vehicle on one side and another vehicle could easily get by on the other side.  Here's a link that even shows some of it: https://urbnparks.com/boston/thoreau-path/

As far as Bowdoin Sq, there was a street sign and those were small pedestrian streets with another sign inside of it for 'Norman Herr Way'.
