Also known as the Limeville Bridge.

Is Anand shared a Marco Delgado photo
Scott Burrell For many years it carried the highest live/dead weight rating of any bridge in existence.
Donald Montgomery Wow, bet it takes 3 months or longer to inspect...

Stu Levene photo:
The seldom-photographed Sciotoville (Limeville) Bridge towers above a CSX train of 129 empty coal hoppers. The shot was taken from on top of the parapet at the south side of the bridge.
Appalachian Railfan photo:
A coal train makes it way westbound (TT Direction) with coal destined for points north as the final light of day is setting over the Ohio River. A scene like this only makes me reflect on a time when it was possible to see C&O Superpower haul miles of black diamonds along this route. What a sight that would have been to see.
"This bridge held the record for longest continuous truss span [775'] in the world from its opening until 1945. See April 2000 Trains Magazine for an article on this bridge." [Bridge Hunter] It was also the heaviest. [Historic Bridges] "It remains today the mightiest bridge ever built from the point of view of its load capacity." [cohs]

One side was built on falsework. Then the cantilever design allowed the other side to be built with minimal falsework because the first side was available to balance it. But the forces on the joints changed between the initial truss structure on the first side and the final cantilevered truss so hydraulic jacks were needed to join some of the members for riveting. The following catches the center pier completed, wooden piers used as falsework, a travelling gantry on the false work to build the supported span, and a creeper hoist on the other side of the center pier to build the suspended span.

"It contains some of the most massive members and chords ever seen in a truss bridge." [Historic Bridges] The following shows a member that requires both booms of the hoisting tower to lift it.

A pictorial summary of the construction stages. As the suspended span grew, they could remove some of the false work under the supported span because it was being held up by the weight of the suspended span. Reducing the number of falsework piers in the river was important in the Winter to reduce the impact of ice flows on the falsework.

The massive size of the members is caught by this photo. I had to look a while before I did find some men in the photo.

Three photos by Dave Honan with the comment:
A couple miles east of Portsmouth, OH, is CSX's massive Sciotoville Bridge, a two-span, 1,550-foot continuous truss bridge over the Ohio River. The structure, the heaviest continuous truss bridge on the continent, was designed by David Steinman and built by Gustav Lindenthal between 1914-17 for the Chesapeake & Ohio Railway.

Here are a few pics from my trips on the Great Northern Subdivision. This bridge shown when I was traveling south and north was made in Germany and floated up the Ohio River many years before my time. It spans the Ohio River between NJ Cabin on the Ky. side and Sciotoville on the Ohio side. It's located at MP CJ 1.5 and is of serious interest to railfans.

 Here is a picture that was given to me. I received it as is with the side text cut off. It was a local resident to the area photo.

In 1994 I caught Milwaukee Road 261 crossing the Ohio River on the CSX (former C&O) Sciotoville bridge returning from pulling the New River train. This was the last year these trains were pulled by steam and 261 was used as NKP 765 was in for a major overhaul.
