Forth Road Bridge main cables: replacement/augmentation study

A first-of-its-kind internal inspection of the Forth Road Bridge's main cables in 2004 revealed significant wire corrosion, prompting a feasibility study for cable replacement or augmentation. The study, commissioned by FETA, evaluated options to mitigate corrosion progression while balancing structural integrity and operational demands. Findings underscored the necessity of retrofitting dehumidification systems and acoustic monitoring to prevent further deterioration, ensuring the bridge's continued functionality as a critical transport artery carrying over 24 million vehicles annually.
