You can go turn left at the five lamps and then over the bridge. coming the other way -south to north however the first turning right is at Summerhill/North Circular Road. Can't figure out what's to be gained. People will avoid the bridge altogether if such restrictions continue.
I was little relieved to see you could turn right onto the bridge from the North Quays but was totally stunned to see you could not turn left from the the Point direction. Never ceases to amaze me how gormless our decision makers are! Complete waste of our money. The rise to power seems to be directly proportional to how well you can talk the talk rather than how well you can solve problems. That's bureaucratic Ireland for you!
