After thinking back over this period, I have realised that the revolution in the design of structures has been nearly as great as the revolution in transport that took place in the previous half-century, which started with horses and ended with jet aircraft! E.W.H. Gifford

This paper gives the background investigation made into the provision of new access systems for two major steel bridges constructed in the early 1950s. The selection process led to a design, construct and erect contract completed in 1989. The paper highlights the problems of providing such a system at this later stage, rather than as part of the original design and maintenance concepts, and sets out the various methods of access possible before discussing the process used to arrive at a final solution.
