One of the Mega Projects underway in the city is the new subway system.  Most of the major streets in the city are obstructed by the construction of this new transportation system.  Circulation in the city has become virtually impossible and the traffic jams are monstrous.  Patience is required whenever you leave the house. This photo shows part of the work underway on  Via España.
