By the end of the 18th century, it was apparent that the old London Bridge — by now over 600 years old — needed to be replaced. It was narrow, decrepit and a hazard to river traffic. In 1799, a competition for designs to replace the old bridge was held, prompting the engineer Thomas Telford to propose a bridge with a single iron arch spanning 600 ft (180 m).
