Over-Truss Steel Bridge

  • 20m - 100m span
  • Very similar to simple beam bridges, but the beams are replaced with trusses, making them much deeper and lighter
  • Easily widened with additional trusses
  • More complex to build
  • Depth is typically 12% of the span, so the roadway has to be higher if the bridge is to have sufficient clearance over water, railways etc.
