AP-7 Highway Extension

The project consisted of the extension of a third and fourth lane along the AP-7 toll highway near Girona. The construction was carried out by widening both the outside and inside of the roadways. All the extensions were carried out with the highway in service and with considerable earthworks in clearing and embankment. The work includes drainage works, bridges and channels, overpasses and underpasses, and the enlargement of three major viaducts: the viaduct over the River Ter, the viaduct over the River Xunclà and the viaduct over the River Guilana.
