This two track span is based on the Boyne Viaduct over the River Boyne in Drogheada
(Droichead Atha in irish), Ireland. This represents the bridge after it was extensivly
re-built in 1932. Rgwe original lattice girder spans were replaced by more modern
spans and the tracks re-arranged into a gaunletlet system. For poly-count reasons this
is a greatly simplified item.
