MILW - Rock River Bridge (1882)

I believe this span is also a Rust & Coolidge span, although the article mentions a double track bridge, and this was not double track until a parallel span was added in 1897. However, R&C did the Sabula bridge on the same line, the same year with the same truss and portal design (other than the skew). I am confident that this one is indeed the R&C bridge mentioned.
