Verdasio bridge

Intragna, Switzerland, 1999-2000

  • Strengthening of the two-span prestressed concrete box girder with four CFRP cables
  • External cables inside the box girder in a polygonal path over the 69-m length of the bridge
  • Cables accessible at any time for examination or replacement
  • Corrosion-resistant strengthening solution
  • Monitoring of the load in the pre-stressing CFRP cables. Very small relaxation and negligible long-term losses in the pre-stress force
