A complete list of bridges in London with pictures. Famous <nationality> bridges, the biggest and the highest. From the earliest arch and beam bridges to the newest suspension and truss bridges, this list has them all. We build bridges to span obstacles, be it a valley, waterway, or another road. A bridge's function designates its design. A bridge can can be temporary, or it can last for millennia. Many Roman bridges are still standing (and even in use) today. No surprise then that bridges often become iconic landmarks for their region.
