Building the Humber Bridge: cable spinning, deck erection, and site challenges

Overview

This webinar offers a rare opportunity to step inside one of the most ambitious civil engineering projects of its time—the construction of the Humber Bridge. Drawing from his six years on site beginning in November 1974, Brian will use original 35mm slides and diagrams to illustrate the challenges, ingenuity, and temporary works that made the bridge possible.

He will describe how 11,000 tonnes of 5mm “bridge wire” were meticulously spun into cables containing 14,948 individual wires, followed by the precise installation of cable bands and suspenders to carry the 18.1m deck sections—most of them lifted directly from the River Humber.

The talk will also reflect on the working practices of the mid-1970s: the advent of the Health and Safety at Work Act in 1974, the reliance on slide rules and steel tapes, and the sheer audacity of achieving such a feat without the digital tools available today.

This is not just a story of technical accomplishment, but of teamwork, resilience, and bold engineering that redefined what was possible.
