How do you judge a bridge? The mighty leaps across wide valleys or the short hop across a creed so as not to endanger life around it. One where we'd drive miles to witness it take on a load while being dazzled by its size and architecture? Stone, steel, concrete, wood? I like some of the short trestling work like on the LV's Southern Central: wood still to this day. I also am astounded by stone of Starrucca and the rock at Rockville and the steel of Moodna and all other which made an engineer dig into his ability to tackle the open space. So, I went with Ed's pic of a wow bridge of steel on a curve in a canyon in the Canadian Rockies as a salute to all bridges and photographers who see the might and beauty in a bridge.
