The project includes the realization of a large-scale multimodal exchange center in the city center in front of the Opera
This new center consists of:
- a new metro station at the intersection of an existing station,
- a large car park,
- a tunnel for cars and trams.
The project also allows for major urban redevelopment of the area in front of the Opera.
During the underground construction works, historical remains were discovered and integrated into the new structure.
The construction of the 4 lane road tunnel suspended from 89 prestressed beams (max. length of 45 m) required more than technical prowess.
The studies took into account the problems arising from construction phasing in order to maintain traffic in the city centre. The metro station under which the work was carried out remained in service.
