There will be one northbound lane open during the closure. All southbound lanes will remain open during this time. Heavy vehicles up to 3.5 metres wide are permitted to travel in both directions.
There will be no northbound access for heavy vehicles wider than 3.5 metres during the eight hour closure.
A reduced speed limit of 40km/h will be in place for the safety of workers and road users.
The closure is to allow for necessary upgrades to be carried out, as a result of the recent severe weather.
