"The chosen concept is essentially a bowstring arch with a top tie; a design that is similar in its structural behaviour to a half-through arch, says Beade. It is a composite structure, with both deck and arch formed of concrete slabs, connected at their edges to a stainless-steel structure with spandrel columns at right angles to the axis of the arch.
The arch and the deck become a single unit over the middle third of the bridge, and this, combined with the wider deck at midspan, creates the structure’s elegant geometry. At the centre of the span, the edge of the structure is only 600mm deep and at the ends of the bridge this increases to 3.1m. The stainless-steel shear studs that connect the concrete deck to the steel structure to make it a composite were specially made by the steel fabricator. “We could have ordered them from a supplier in the US,” says Mitchell, “but it would have taken too long to import them.”  Click image to enlarge Duplex stainless steel was selected not just for durability and maintenance reasons, but also because its strength-to-weight ratio enabled a lighter structure that could be lifted into place as a single piece."

"Duplex stainless steels are increasingly used as structural materials in building and architecture because of their exceptional mechanical properties. Their room temperature yield strength in the solution annealed condition is more than twice that of standard austenitic stainless steels not alloyed with nitrogen. Over the last few years, they have started playing an increasingly important role in the construction of bridges, wherever specific environmental conditions combine with the need for high load-bearing capability. Duplex stainless steels are mostly selected because of their combination of high strength and corrosion resistance. Their full potential is used in locations where the material comes into contact with salt water, or where high concentrations of chlorides are present in the ambient air or where de-icing salts are of a concern. The higher initial costs involved in choosing duplex stainless steel as compared to conventional structural steel are more than compensated by longer life span and significantly lower maintenance and repair costs. Their full recyclability makes them more sustainable than non-metallic solutions. Several recent examples of using duplex stainless steels in bridge construction are presented." https://www.worldstainless.org/Files/issf/...ridges.pdf |

Just came across this and thought others may be equally intrigued :
