SBC or Stony Brook Conduit
As I mentioned in the old Boston Drain thread, the SBC is to date the largest drain in Boston that we have read about and explored. Stretching more or less 7 miles from it's inlet in Hyde Park to its outfall in the Back Bay Fens. It is fed by many small brooks, and some larger ones. Goldsmith Brook (Arnold Gold), The Roslindale Branch (Rozzie Branch), Bussey Brook, and The Canterbury Brook (Canterbury Branch) are a few of the larger ones we've encountered so far. We first explored The SBC back in December of 2009 and up until that point all the drains we'd found were no more than 6 or 7ft tall. So that initial glimpse of a tunnel approx 12ft wide by 17ft tall was quite awe inspiring.
Our first time into SBC was through Bussey Brook. Bussey Brook used to end in a set of steps that dropped into a short stretch of tunnel that met with Stony. But in the late 1980s with the creation of the southwest corridor the entire run of Bussey had to be lowered. From it's inlet to where it meets that short original stretch, it has been replaced with twin 5ft RCP.
Sometime around 2010 Fox25 news did a report on Stony Brook and I grabbed these historic pictures from their online version of the story.
Now for a couple originals:
