|September 2013 (35.6970 Degrees, 139.9329 Degrees) Utility and Railroad Bridges|
The next three bridges across the Edogawa are two utility bridges with a railway bridge between them. The first utility bridge carries a single pipeline across the river. However, the next utility bridge carries two pipelines and so it switches from a truss segments to steel arches to carry the bigger load across the river.
The railroad bridge is made up of Warren Truss segments sitting on two column bents. They probably build these trusses in a yard and bring them downstream on crane barges that lift them into place. A top chord piece is placed between the segments to make a continuous superstructure.
The Google Earth photo below shows the location of these three steel bridges. The Edogawa has become a salt water estuary as we get closer to Tokyo Bay.Tokyo Prefecture, Japan's Bridge's: Utility and Railroad Bridges across the Edogawa
