Description

The underground M-30 was part of the works necessary for remodelling the urban highway in Madrid, with a length of 3,347 meters.

The work consisted of burying 1,666 meters of roadway; twoway three lanes, that link to the south bypass; and two, twolane routes to the southern junction.

The works were of distinct technical complexity, requiring careful planning and coordination of the various jobs. FCC overcame this to complete the project four months ahead of schedule.
