Hi again,
I am not so sure, but I think there is no thread about the biggest project of the new Madrid mayor: Alberto Ruiz Gallardon, the main promotor of the biggest subway extensions ever made in the world during his 8 years of Madrid region goverment.
Now He has a new incredible project, he will erase the traffic jams of the famous M-30 ringway expanding it trough the underground, how?, probably you can find more details inside some related webs, but I can advance you some points:
1- All the track between "Puente de los Franceses" till "Nudo Sur" will be fully underground, it means no cars outside!!, he will cover the way with a riviera park, the madrid citizens will can go back for enjoying the Manzanares river with a picnic, meanwhile the cars are running some meters below.
2- Some by-passes will let the M-30 to have extra corridors in some critical points, so cars going into N-V will can use a new corridor (underground too) and the rest of the cars will use the old part.
3- The traffic lights of the north M-30 will dissapear, so the M-30 will be completely finished.
Now we can add the excellent subway system, new lines under construction, the new Cercanias tunnel between Atocha and Chamartin and some new trams in conflictive ways and probably Madrid will can say good bye to the traffic jams.
It sounds like a dream, but it could be true because day trought day I see that the traffic jams are being moved to the outside cities.
Bye.
