Granollers Ring Road Covering
Service: Detailed Design
Client: GISA – Infrastructure Administration of Catalonia
Period: 2003 – 2005
GPO was awarded with the detailed design for a 717 m segment of the Granollers bypass. The objective of the project was to prevent long vehicles from circulating on the surface of urban areas.
Since the new road crossed under two roundabouts in the road N-152a and under the Francesc Marcia roundabout, the design included bypasses which linked both roundabouts on surface with the underground segment. Three longitudinal structural solutions were defined to adapt the project to the geometry of the underground road, the surface lanes and the existing infrastructures.
