Night works are planned for Sunday 18 April to remove temporary roadside barriers on the northern side of the roundabout, to allow crews to construct a traffic
island.

Due to the location of the temporary barriers, manual traffic control will include SH1 and SH15 traffic.

southbound lanes.SH1 – Dome Valley safety improvements
