I am marvelling at the engineering skill of building bridges for horses that survive today’s traffic 170 years later.
William Tierney Clarke (1783 - 1852) engineer designer of chain link suspension bridges built the Marlow, Hammersmith and Széchenyi Chain Bridges.
When the Széchenyi bridge across the Danube in Budapest (lhs in the photo) opened in 1849 it was the largest span suspension bridge of its type in the world. It was a strategic target in the Hungarian war and it even withstood the tramping of 60,000 troops with their cannons.
The Hammersmith Bridge opened in 1824 but is struggling today having served beyond its aims.
The Marlow Bridge (rhs and middle photos) in my hometown survives with careful support from the local council (it was closed for 6 months after an errant 32 wheeler lorry got stuck - max load is 2.5 tonnes!).
