I don´t know of anyone heading towards Spain, but just in case ...

>From today, 3rd of June, the metro line from Barajas airport into Madrid will be closed between the stations of Colombia and Mar de Cristal. You can get a free PDF brochure explaining all of this (there is an english version) at: http://tinyurl.com/quetb

The english version is at the very bottom of the page. There will also be people at the airport (the green jackets) explaining all of this.
