These two scans are pictures of bridges along the Shawmut.
The construction picture was taken near Brentwood Camp and predates the Shawmut.
The second bridge would have been located between Angelica Creek and the present day Expressway. Not far from the Angelica Cemetery. The abutments are still visible.
Ron, these pictures are all from the Joncy area very near where Chris Hoffmann lived.
The Alton Sylor bridge (above) replaced the one labeled 3rd bridge (below).
