I can tell you almost nothing about this bridge. It's just a big viaduct which carries the railway across the River Rhone at Avignon.
It lies relatively close to the water, and so gives some idea of the river's scale. At this point, the river is about 450m wide, and the bridge totals about 560m long, as it also spans highways and flood defences on both banks. Each individual span is about 75m.
The bridge is brilliant in its single-mindedness, comprising braced steel lattice truss girders unvarying in height, supported on masonry piers within the river. There's often something exquisitely beautiful about a bridge which appears to make no concession to beauty.
The most visually interesting feature of the bridge is surely one which was unintentional. The latticework on the trusses uses large diagonal elements which are formed out of steel angles. These inevitably create a pattern of light and shadow on the face of the girders. The arrangement has been alternated between spans, so that on a sunny day, each span of the bridge appears to alternative between a dark and light colour (third photo below).
