Wooden bridge

The 3D bridges are very old structures that span a 3D valley, road, body of water, or other physical obstacle, and provide passage over the obstacle. The first 3D bridges were made by 3D nature itself so, they were 3D logs fallen across a 3D stream or 3D stones in the river. Thus, the first 3D bridges made by 3D humans were made of either 3D wooden logs or planks and 3D stones. And here is a 3D Wooden bridge that is very old yet very functional. So, not only 3D pedestrians can pass over the 3D Wooden bridge but some small 3D vehicles too.
