The collapse of a wall of natural rock at the entrance to Parque de La Reina at 3.45pm not only closed the road itself but also caused long tailbacks on the TF1. Thankfully only one car was damaged, and no people were hurt, but it was a lucky escape for one bus full of children. Sources say that this example shows the vulnerability of such walls, and stressed that this collapse occurred in dry weather, saying that the risk is clearly considerably greater in heavy rain. What the solution is when such walls are commonplace, I don’t know.


  1. So many more accidents waiting to happen. I hold my breath every time I drive past the already partially collapsed walls at the Puerto Santiago roundabout and on the TF47 between Callao Salvaje and San Juan. Major roads with high traffic flows. Money won’t be allocated until there is serious injury or death.

  2. Would you like to point out where the roundabout is you are talking about.I,m not aware of a roundabout on this road except at the entrance into Callao Salvaje and at the San Juan exit at the end nearest to heading for P. Santiago ….

  3. The only partial collapse I can think of on that road is just past the new area after Callao Salvaje. I have to agree though it is a worry and all the council have done is put a fence up with some lights and painted the fallen rocks white. Hardly inspires confidence in using that road

    The thing is that these types of “walls” are everywhere here. They’re an inevitable result of having to make a cut through volcanic rock to create the road, and volcanic rock is a mix of ridiculously hard & heavy and extremely crumbly & light. We’ve had this up the mountain where we’ve created a garden, and some rock just cannot even be drilled into, whereas in other parts it can just be scraped away with bare hands, crumbling almost like earth.
    Then there is the “cinders” type material in lava tubes, which will be an issue wherever a road has been cut. Start looking out for curved shallow-arch-type markings on the walls … once you’ve identified them, you’ll see them absolutely everywhere. These are, essentially, unexcavated caves, and the material inside is cinders. And nothing crumbles like cinders because it’s not even really solid. What is the solution? Concrete spray everywhere might do it, but the added cost (never mind the look of it) would be prohibitive. They put nets up in some parts but that doesn’t resolve the problem, just catches the fallers.

  5. Janet, as you have said these rock walls are all over the Island, what I do not understand how the Councils keep ignoring them, look what happend on the Los Gigantes beach, also the Fisher lady statue,lovely but the rocks are crumbling around her sometimes blocking the road which is then cleared plastic tape put around waiting for the next fall.
    When are the people who make these decisions going to take responsibility for their actions before somebody gets killed again

    I think it’s just a question of money, M, and a tendency to bury their heads in the sand (unfortunate expression really given the circumstances but you know what I mean).
