Sunday we had wandered down to Port Adelaide 14km from the city of Adelaide to observe Wonderwall Art Festival (very arty weekend after the sculptures on Saturday). Decided to take a break for lunch and sitting eating pancakes watched as the bridge opened to let the tall masted yacht go through. Then three other yachts passed through in the opposite direction - traffic was building up either side and the bridge stayed open. Unfortunately for those in cars waiting either side there seemed to be a technical hitch as the bridge stayed up at least 15 minutes after the boats have passed.
