The Maintenance of Silver Jubilee Bridge, UK
The Grade II listed Silver Jubilee Bridge is a two-pinned steel arch bridge with continuous side spans spanning the River Mersey and Manchester Ship Canal. With a main span of 330 m, it is one of the largest steel arch bridges in the world. Since construction in 1961, Mott MacDonald has been employed on numerous refurbishment and strengthening commissions on the bridge to the various bridge maintainers, currently Halton Borough Council. The bridge is currently closed undergoing major refurbishment works with traffic using the recently opened Mersey Gateway Bridge 2 km upstream. Silver Jubilee Bridge is planned to reopen late 2019.
This paper presents a case study highlighting the challenges in maintaining an ionic long-span arch bridge. Recent refurbishment works described include new maintenance gantries, cathodic protection, maintenance of the locked coil cables and the challenge of maintenance painting.
