Roe Highway

Light in the fast lane

An artist-designed exterior lightwork, which makes up the seventh and final stage of the Roe Highway development in Western Australia. The seven Entry Statement Poles each incorporate a Thorn lantern with 250W HPS optics making not only a public artwork depicting the number 7 in shape, but providing a functional part of the lighting scheme. The landmark elements are painted a gold colour - inspired by the native WA Christmas Tree, Nuytsia floribunda - and signal the location of the on/off ramps near Kwinana. They portray the future without any sense of inappropriateness.

Overall some 750 standard Thorn aluminium lanterns were used for the highway and shared paths. All use energy efficient high pressure sodium lamps.

"Thorn’s road lantern with Optibloc optics was selected because of its excellent photometrics," says Ivan Semmler, lighting designer at Maunsells." Also the ability to adjust the lamp holder to suit different situations such as varying road widths and still give maximum spacings is a great advantage. Similarly the Thorn Civic for the Shared Path lighting was selected for it’s photometric and mechanical abilities including vandal resistant performance."

The project was by the Roe7 Alliance, a collaboration between Main Roads Western Australia, designers Maunsell and constructors Clough.
