The design is intended as a foil to the massive stone bulk of Sir Giles Gilbert Scott's building. It takes the form of a slender S-shape of steel tubing that snakes around a deck and balustrading constructed in transparent glass. Starting at the cathedral end, a tied arch rises above the flat bridge deck, then flips down seamlessly into a 'bow-slung' truss beneath it. The arch's S-shaped outer rim of tubular steel snakes around the deck in one continuous bow. Steel struts running from the arch support the load of the bridge deck, with those rising above the deck working in tension, and those below in compression.
