thank you for sharing so many wonderful types of bridges with night scene as the background... "The first bridges were made by nature itself — as simple as a log fallen across a stream or stones in the river. The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement." Amazing how nature can inspire men to built some famous bridges of today.  |
