What is a cantilever bridge?
Q: What is a cantilever bridge?
A: A cantilever bridge is a bridge built using a cantilever, which is only supported on one end.
Q: What may be used as cantilevers for small footbridges?
A: For small footbridges, the cantilevers may be simple beams.
Q: What are the cantilevers made of for large cantilever bridges designed for road or rail traffic?
A: For large cantilever bridges designed for road or rail traffic, the cantilevers are trusses built from structural steel or box girders built from prestressed concrete.
Q: What advantage do steel truss cantilever bridges have when compared to other types of bridges?
A: Steel truss cantilever bridges have the advantage of being able to span distances of over 1,500 feet, making them a major engineering breakthrough.
Q: What difficult crossings can cantilever bridges be built at more easily than other types of bridges?
A: Cantilever bridges can be more easily built at difficult crossings because they do not need to be supported during the construction.
Q: How does a cantilever work as a bridge support?
A: A cantilever is a support that is only supported on one end, and can extend out from a structure to provide support for a bridge.
Q: What is the difference between the cantilevers used in small and large cantilever bridges?
A: For small footbridges, the cantilevers may be simple beams, whereas for large cantilever bridges designed for road or rail traffic, the cantilevers are trusses built from structural steel or box girders built from prestressed concrete.
