There's a bit of road through Pullenvale on my commute in that's been undergoing major roadworks for at least 6 months, maybe more, and has a massive line of traffic every single morning. Of course, for bikes that's no biggie - it's single lane, but there's a nice wide hard shoulder outside the white 'fog lane'. Probably slightly illegal, but it's not a breakdown lane, so it's fairly typical to cruise up there and get to the front. But this morning they'd put 3 or 4 road work signs in that area so that they came right up to the white line. They'd be maybe 20 m apart, so it's possible to head up there but you have to drop back into the traffic every 20 yards to miss the signs. Not sure whether they did it deliberately to stop bikes, or whether that was just where they wanted to put them and riders didn't enter their tiny minds. PITA either way.
