Supreme Award for Structural Engineering Excellence for the Tamina Canyon Crossing

The Tamina Canyon Crossing in Bad Ragaz, Canton St. Gallen, Switzerland received the Supreme Award for Structural Engineering Excellence 2018 by the Institution of Structural Engineers.

The Supreme Award for Structural Engineering Excellence goes to the "finest example of excellence in structural engineering design", selected by the judges from the winners of the twelve principal Awards categories.

Judge's comment:

“The Tamina Canyon Crossing is a beautifully executed arch bridge. Its form complements its picturesque surroundings and the geology of the gorge. With few alternatives for suitable springing points, the final form is asymmetric, which added complexity to the structural engineering challenge.

To ensure that every aspect of the bridge structure was pared down to the barest minimum, the five struts are inclined, rather than the more usual vertical. The two end struts are fixed to the deck, creating a helpful portal-frame action, while the other three struts are pinned at their ends. This innovation offered the opportunity to reduce span lengths in the deck without needing to add more struts.

Tamina Crossing oozes structural innovation, and results in an efficient, durable and robust structure. But, most importantly, it results in a beautiful bridge, which satisfies all of Fritz Leonhardt’s rules for the aesthetics of bridges. The achievement of such beauty against the backdrop of a tremendously difficult terrain, using ingenuity alone, is the hallmark of great structural engineering.“

The Award Ceremony has taken place at The Brewery in London last Friday.
