Maintaining the Silver Jubilee Bridge: Cathodic Protection for a Critical Causeway

Constructed in the 1960s, Runcorn, United Kingdom's Silver Jubilee Bridge, an arch bridge with two side spans, carries 90,000 vehicles on its four lanes each day as part of a northwestern England highway route. Chloride attack and carbonation have both affected Silver Jubilee Bridge's reinforced concrete approach viaducts. The authors discuss remediation through 1992 holding repairs and 1993 and onward cathodic protection. Checking to see if there has been alteration to anything electronically significant is done by using reference electrodes (or half-cell) probes as basic remediation monitoring for all cathodic protection systems. The authors discuss tailoring a rolling repair program to suit available funding. Basing this rolling program on cathodic protection has allowed repair and rerepair cycles once commonplace in chloride-contaminated concrete structure remediation to be broken.
