Thousands of people have poured through the new Adelaide Street tunnel beneath Brisbane’s CBD for a community open day, five days before it officially takes its first bus and metro traffic. Gavin, who took his family along, described it as “a really nice tunnel”. “I think the electrical installation is probably the best in the world,” he quipped, adding that he was the project manager who had worked on it.
