Aquaducts and Viaducts (in colour)

Brief

In this contest I would like to see your best colour photos of aquaducts and viaducts. A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated span. They could be for either road or rail transport, generally crossing low-lying ground such as valleys or canyons. Aquaducts are the same, except being constructed to carry water. These can be close up shots showing detailed parts of their construction or wide landscape shots, but it must be clear they are specifically viaducts or aquaducts, not just regular bridges. Colour photos only please. I very much look forward to seeing your entries.
