Project: Smart Stay Cable Upgrade for the Guadiana Bridge

The Guadiana International Bridge, spanning 666m with a 324m central span, connects Spain and Portugal. After multiple strand failures, inspections in 2018 confirmed the need for a full stay cable system replacement.
DYWIDAG’s Role:
  • Inspection & testing (June – Aug 2018)
  • Stay cable replacement (Nov 2019 – Apr 2021)
The replacement involved removing old cables, modifying anchorages, and installing new DYWIDAG monitoring stay cables with sensors for continuous force measurement. The system includes elasto-magnetic sensors, cable vibration dampers, and automated force monitoring.

With completion in April 2021, the bridge is now safer, stronger, and equipped with smart monitoring technology.
