A couple of people have said that they have seen buses (normal ones, not school ones) going along Calle Alcor. Also, they have said that some concrete seats and bus signs appear to be ready to deploy on Calle Alcor.
So it seems that perhaps one or more of the local buses may be being diverted to go along Calle Alcor between D'Bar and Velas Blancas.
I have just checked the Situame app and nothing has changed on that. If I do hear of any official changes to the routes I will publish details here.
