The Leichhardt Council area has had them for some time - artistically decorated RTA traffic light cabinets. Normally, these cabinets are a dull grey, enlivened quite regularly with a variety of graffiti tags. Rather than endlessly paint them to cover the tags, the RTA allows Councils to decorate them with public art.
There are a lot of these cabinets around Canada Bay - every set of traffic lights has one. Council made a start this week by working on half a dozen of them in an area that is high visibility (in terms of passing traffic) and high impact (in terms of the amount of graffiti applied).
It's a great start - I hope to see more of it in future.
