Work
the construction company carried out excavation work in a careful way, since there is little coverage of rock above the tunnel, this forced to work slowly, but guaranteeing security.

The Austrian method is a way of completely underground excavation, which allows to minimize all interference from the surface. The excavation works were used to milling machines with 60 tons on two fronts to speed up the construction.

the work of excavation had a monthly preview of 150 metres between the two portals, according to the technicians of the company u000abuilding this kind of work reduced to a minimum the damage to the environment.

The tunnel which connects the UASD is the first in its category in Dominican Republic with depth that exceeds 25 m below the buildings and facilities of the area.

Two fronts of work were established for the construction of this viaduct. The first front from the Ortega y Gasset intersection with February 27 (North Portal) towards the UASD and the second front since the street Thomas Aquinas with José Contreras in the University area (Portal South) towards the Ortega y Gasset.

The tunnel towards the UASD will provide a new road connection towards the North-South, starting from the corner formed by the streets February 27 with José Ortega y Gasset, reaching the intersection of avenida José Contreras with the Santo Tomás de Aquino.

viaduct was completed on time in u000athe contract, and the timetable of work.
