• Arch bridge:

  • A concrete arch takes the load on the bridge by using compression.

  A) Arch Bridge

  
• Cable Stayed Bridge:

  • The bridge is held up/suspended in the air by using high tension metal cables, fixed onto a concrete strut.
  • This functions because concrete is resistant to compression and steel wire is resistant to tension.

  
• Arch Suspension Bridge:

  • The arch is made of a triangulated metal frame, which takes the weight of the bridge
  • The bridge weight is suspended in the air with metal cables connected to the arch
