Are glass bridges a good idea?

I still prefer that the foundations of the bridge be made of hardened steel. Glass may be hard but it is brittle. One minute crack could cause a wide fracture and collapse.
Consider the impact of weather changes such as falling snow or hail stones. Nothing man made lasts forever, things degrade with time. The safety of people is a top concern instead of the opportunity to show off or attract tourists.
