Wrong location, water is in cave. I added the correct location as cave entry.

Signs say it is not allowed to pass the bridge even as a pedestrian.
It is in very bad condition.
If the water is low you might be able to cross below the bridge but not with a vehicle. You would have to go all the way back to the main road and enter Calle Radio Cima from there.

"its exactly on the other side of the street."
