One of the most pictured objects in Trondheim, and probably the most painted.
Also called Lykkens portal, "Portal to happiness".
The bridge crosses the river Nidelven. Total length in 82 m. An 8 m long part of the bridge between the red portals can be be lifted up to let boats taller than 8 m pass. I have never seen that happen, but the portals are quite decorative.
