A bridge in Trento at night, as seen from the balcony of my hotel in Sardagna. In the upper left-hand corner is the railroad station shown in one of my earlier submissions; next to it in the upper center is the bus station. At first I didn't submit this photo because I didn't think it was eligible, but after checking a dictionary, I now believe it is. A bridge conveys traffic in the same sense that a pipe conveys water.
