A lot of people criticised the tunnel extension into the city. After all, it only saved ~5 minutes of travel time. I don't think most people in Adelaide fully appreciate public transport yet.
Adelaide is often called the 20 minute city because you can just drive anywhere in under that. But that's changing as our population grows. I really hope there are more projects like this that get funded.
Adelaide used to have _the most extensive tram network in Australia_. It was pulled up around the same time as Sydney pulled theirs but Melbourne didn't (because they're the original hipster). Sydney had the money to reinstall theirs but not Adelaide. There's a lot of politics around fixing our trams - we almost dropped 40 million on a building a right hand turn.
