The work consisted of burying 1,666 meters: two tunnels of three lanes traffic lanes, that link to the south bypass and two others with two lanes, which go to the south node. For implementation the “Cut & Cover” method was used.This complex engineering project required careful planning and
coordination of the different activities which attained successful completion four months ahead of schedule


This project will improve air quality, reducing CO2 emissions by an average of 14 tons per day.


Some of the project benefits include; recovery of the Manzanares river bank, freeing it from vehicular traffic and restoring pedestrian footpaths whilst creating a large green corridor.
