  • 5. How does Toni choose sites?
    • Toni evaluates villages that are suffering for lack of a bridge.
    • Toni engages the communities in implementing bridge projects.
    • The personal involvement of community members ensures the success and long term sustainability of the project.

    • Toni has constructed over 230 of these bridges
  • 9. Why suspension bridges?
    • Suspension bridges can be constructed relatively cheaply compared to other bridge types.
    • Bridge elements can be fabricated off-site and quickly erected.
    • Bridges can be constructed without heavy lifting equipment.

  • 15. Toni’s Implementation Method: Timeline
    • Planning:
    • Bridge layout is planned and marked
    • Excavation:
    • Community members excavate for foundations and gather sand and stone for concrete
    • Tower fabrication:
    • Bridge elements are usually welded off-site by Toni’s assistants
  • 16. Toni’s Implementation Method: Timeline
    • Erection:
    • Towers are erected in foundations and set in concrete
    • Cables:
