This is a view of the Pont d’Iena in Paris from underneath, showing the multiple sets of piers and girders. I really do like looking at the inner workings of things, but this picture actually was made because I was struck by the strong shapes and contrasting colors.
The bridge is both old and new: Built starting in 1808 on Napoleon’s orders, it was widened from 14 to 35 meters in 1937, in time for the World’s Fair that had sites on both banks of the river. As you can see at the right edge, it’s also the bridge closest to the Eiffel Tower.
