Highway infrastructure usually calls to mind a bland blur of concrete - but the city of Melbourne has turned a standard freeway connection into a new and memorable art form. Entitled the Craigieburn Bypass, the artistic freeway sculpture was designed by architects Tonkin Zulaikha Greer in collaboration with landscape architecture firm Taylor Cullity Lethlean and artist Robert Owen. The award-winning design consists of three long sculptural sound walls punctuated by a pedestrian bridge and a Corten steel arc that sweeps across the freeway and creates a grand visual gateway into northern Melbourne.
Designed to be experienced at high speeds of 110 kilometers per hour, the site-specific sculptural sound walls use repetition, contrasting colors and undulating shapes to create a sense of dynamic movement.
The first set of sculptural sound walls is composed of an undulating wave plated with Corten steel shaped into simple concave and convex folds.
In contrast to the first, the second set of sound walls exchanges red hues for a series of repeating blue blades set in front of a long translucent, edge-lit acrylic wall sandblasted with a digital pattern.
The rust-hued colors reference the earthen surroundings and imbue warmth into the freeway landscape.
