Casting such large parts was complicated and required skills developed over generations.
What was the main problem with iron bridges?

The Tay Bridge in Scotland in 1879 was one of the most serious examples of such a collapse. The center portion of the bridge collapsed taking a train with it during a violent storm.

The measures were put in place by Telford & Wrekin Council to help more businesses to open safely after lockdown.
Why was cast iron used in bridge construction?
Cast iron has good compressive strength and was successfully used for structural components that were largely in compression in well-designed bridges and buildings.
