Dst is the main contractor responsible for an upgrade of one of the capital's busiest roads, the 'Segunda Circular'.
Dst is handling the project to upgrade Lisbon's Segunda Circular, particularly a connecting viaduct over the present split-level crossing between Avenida Padre Cruz and the Segunda Circular, which is going to be connected to Avenida do Campo Grande.
The contract represents a turnover of €1.5 million for the dst group.
The works are being carried out on two spans of almost 63 metres in length and also include a new connection under the viaduct between the Segunda Circular and Avenida Padre Cruz.
This new connection, which aims to overcome the difference in level between the two avenues and ensure an alignment that is very close to the capital's circular, means a retaining wall has to be built to support the volume of earth.
