Although you have to make a slight detour, it is worth visiting this bridge and taking a photo on it if you want.

The 2700m tunnel is impressive and seems to never end. Advice: Bring clothes at least when passing through this tunnel as it is cool. Otherwise there is automatic lighting.

That bridge is called "INTUIA-ko zubia" the INTUIA farmhouse is next to it. The misnamed "witches' bridge" is called UNANIBI-ko zubia, right in the Otita park (beginning of the Leitzaran valley). Don't forget to bring lights to cross the numerous tunnels in this valley!! Not to see but to be seen.
