Brosseau Road Bridge
Posted January 30, 2010, by Matthew Lohry (mmlohry [at] comcast [dot] net)

In case there are questions regarding the status of this historic bridge, it was demolished and replaced back in 1998. The replacement is a mundane concrete stringer bridge with no decorative features whatsoever. On a bright note, the new bridge sits next to a pair of massive deck truss railroad bridges, which help greatly to retain some aesthetic qualities at this location.
