Located near the long forgotten station of Pine River south of Merrill, this pony truss crosses the Pine River.
Originally built in 1900 as part of a three span bridge over the Wapsipinicon River at Olin, Iowa; this span was here in 1913. The other two spans were moved to the New Wood River line north of Merrill.
The bridge consists of a 6-panel, pin connected Pratt Pony Truss, set onto timber piers and approached by trestle
At least one other span from Olin is known to exist, located near Menomonie, Wisconsin. The third span was reused at Bridge #G-1904 across the New Wood River on the same line as the Copper River Bridge, but it is unknown what happened to that span.
Railroads oftentimes reused material, particularly along branch lines. This truss design was a standard design, and dozens were constructed. Today, many still exist.
The author has ranked this bridge as being moderately significant, due to the truss design.
