This small bridge is always interesting to look at because it blends in well with the surroundings. The two elements on the left and right are made of solid stone, while the bridge itself is constructed of wood.

Nice as a stage stop. A nice little stone staircase down into the water, which is very decorative. Here there is also runoff from the Ulsrudvannet in a stream under the road. If you are observant enough, you will see that there are a lot of fugitive boxes hung up in the trees around here.
