That probably won’t happen, that’s very unlikely. The next best case scenario is that the monitoring shows there is no movement. If the monitoring shows that there’s no movement at all after a period of time, perhaps two or three days, we’d be happy to open it to single lane alternating traffic,” says Oliver.
