In 1871 the Baltimore & Ohio Railroad built a large multi-span bridge over the Ohio River connecting Benwood,
Virginia and Bellaire, Ohio. The through truss central spans are necessary as the Ohio river is navigable at this point and water level
changes considerably with the seasons. This model was done from a photo taken in 1875 which shows the structure consisting of (from
right to left in the photo) 4 bollman deck trusses, 3 lattice deck trusses, A 300 ft thru lattice truss, a 200 ft thru lattice truss, 1 lattice
deck truss, 2 bollman deck trusses, and a stone arch causeway with at least 20 arch sections. The photo doesn't show the right end of
the structure but it probably had a stone arch causeway too. The river valley is terraced (stepped) in height above the water requiring
different height piers. At 1660 ft this is a high poly-count item. Down-loaders may add causeways if desired. The photo shows the
causeway curving to the left and tracks on both sides paralleling the river at different heights. All spans are of iron construction. This is
NOT a heavy duty bridge. Engines were limited to light weight 4-6-0's to 2-8-0's or smaller with 4-4-0's being the most common. A
slow order was probably in effect when crossing this span.
