A22 Highway viaducts. Stretch Lagos-Lagoa-Alcantarilha

Algarve, Portugal

Structural typology: ROAD & HIGHWAY BRIDGES
Date: December, 2003
Scope: detailed design

Detailed design of 11 viaducts, 30 overpasses or underpasses and a cut-and-cover tunnel. The deck typology of the viaducts includes 2 precast concrete U-beams, which are subsequently continued by means of post-tensioning with high yield bars. The viaducts have dampers in the abutments to dissipate seismic forces.
