AOC Architects’ ultra-high performance concrete footbridge on Dřetovice stream

Conceived as a sort of “magic portal” between the land of the living and the realm of the dead, the Dřetovice stream footbridge, in the Czech Republic, connects the village of Vrapice with its cemetery.
Designed by AOC Architects, the bridge pushes building technology to the limit; the use of freeze-resistant and fiber-reinforced ultra-high performance concrete (UHPC) helped reduce the structural shell thickness. The result is an elegant landscape object – 10 meters long and 1.5 meters wide – weighing less than 3.5 tonnes. The dark gray color of the bridge was obtained by adding mineral pigments to the concrete mix, while the surface was finished by etching and hand sanding.
