The Craigieburn Bypass on the Hume Freeway in Melbourne VIC, Australia was designed by the architectural practices of Taylor Cullity Lethlean and Tonkin Zulaikha Greer with sound walls and road furniture spreading over 32 km.
The elements and concept design was also created with the aid of the artist and sculptor Robert Owen and the idea of the project wasn’t to experience it while standing near it, but rather at a speed of 110 km per hour.
There are three series of sculptural sound walls, a pedestrian bridge and they also include a set of design parameters for road bridges, crash barriers and retaining structures which are common for all roads.
The walls created by Tonkin Zulaikha Greer spread over 2 kilometers and are made with austenitic steel sheets which were modeled in concave or convex folds and placed on a dark concrete base.
The walls created by Taylor Cullity Lethlean are translucent and they preserve the light from the residential areas. This portion is made with edge-lit acrylic sandblasted with a digital pattern with an overlay of precast concrete blades.
