"The Vibrant Laneways program has been successful in using some of Brisbane's forgotten spaces to create pedestrian links and spaces where people can meet and enjoy artwork and amenities." From the Brisbane City Council website.
You can find a list of the many laneways and learn about the projects. It is a good idea to visit during the weekend, when there are less people in the city and you can enjoy the art and precincts in the city at a leisurely pace. Choose a cooler day than I did!
