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.
