Described as being 'one of the finest pieces of architectural iron-work in the world', the High Level Bridge in the UK recently underwent a major programme of investigation, assessment, strengthening and refurbishment. Constructed in 1849, the two-tier, 412m long, six-span High Level Bridge now carries two railway lines, road traffic, and pedestrians, across the River Tyne in the heart of Newcastle City Centre in the UK. This cast iron heritage structure, designed by Robert Stephenson, now more than 160 years old was considered by some to be ‘life expired’ as a functioning structure.

This paper describes how enhanced assessment and testing techniques were used to reduce intrusive strengthening works and extend the useful life of this iconic heritage structure.
