My bridge

The Arrábida bridge, Porto, Portugal, built in 1963, is a splendid example of the modern architecture.

A story behind: This is another thing that I am recently very interested in: slow shutter speed - long exposure photos. 
The fast moving clouds on the slow shutter speed of 48 seconds make an image more dynamic.
