As the 18th century came to a close and the Industrial Revolution was well-established, the only river crossing at Rochester was still a narrow stone medieval bridge which had been built in 1393 through charitable donations. In 1792, the Wardens of the Bridge appointed their first salaried engineer and began a process of modernisation and innovation under the guidance of some of the most important and impressive civil engineers of the day, including Rennie, Telford and Sir William Cubitt. By the turn of the 20th century the medieval bridge had been replaced by the substantial and highly-decorated Old Bridge that is still in use as the only road crossing on the A2 from Rochester to Strood today.
This lecture will explore the evolution of Rochester Bridge, a story which reflected much of the wider change going on in the 19th century bridge engineering profession. It will also explain the political and social background to the changes and how the ancient charity which owns and maintains the bridge was also forced to evolve as the demands for efficient road and river traffic grew.
