Why did engineers choose suspension bridge to crosses River Thames in London?

Engineers chose a suspension bridge for crossing the River Thames in London primarily due to its ability to span long distances without the need for numerous supporting piers in the water, which could disrupt navigation and shipping. The flexibility of suspension bridges also allows them to withstand dynamic forces, such as wind and traffic, making them ideal for urban settings. Additionally, the aesthetic appeal of suspension bridges can enhance the visual landscape of iconic locations like the Thames.
