There are roadworks on King William Street in the city opposite the Commonwealth bank building. Why they are there I do not know. At the moment, the equivalent of a lane of traffic has been closed. A bus stop is also out of action.
The interesting thing is that, certainly on my biased observations, it has made no difference at all to traffic during our 15 minute rush hour. Just as extending the tram from Victoria Square made no real difference to it.
Just goes to show that there is plenty of capacity for wide Danish-style bike lanes raised above other traffic
