Reminder – tidal flow lane control system go-live tomorrow (19 May 6am)
We’ll be switching on the new tidal flow lane control system tomorrow.
From 6am Tuesday 19 May we will once again be able to change the direction of traffic via the overhead signals.
From 6am tomorrow, road users must obey the overhead signals. The signals will display which lane drivers must be in.
Until then, please continue to stay in lane.
