Night works are planned early next month that will see State Highway 1 Ngauranga Gorge closed to southbound traffic between Johnsonville southbound offramp and Ngauranga Interchange.
The highway’s southbound lanes will be closed for two nights – Sunday, 2 February and Monday, 3 February, between 9 pm and 4:30 am.
Roxanne Hilliard, Wellington Transport Alliance Manager, says the middle lane of the highway is to be resurfaced.
“This is a steep section of the highway, where vehicles descend towards Wellington. It is not possible to safely keep other lanes open while we carry out work, so a full directional closure is needed to complete this work.”
“The closure will let us finish this work faster and, because it will be done at night when fewer vehicles are on the road, there will be less impact on drivers,” Ms Hilliard says.
A local detour will be available, and Ms Hilliard says it is important they are followed correctly.
“Light vehicles will be able to take the Johnsonville southbound offramp and detour to the city via Johnsonville, Khandallah, and the Ngaio Gorge. If you are travelling to the Hutt from SH1 you will need to take the SH58 detour via Transmission Gully.”“However, this route is not suitable for heavy vehicles because of a height restriction on the Johnsonville underpass. They must use State Highway 58 to Haywards Hill and State Highway2 Hutt Valley to get to the city. These detours are longer, so drivers should allow for extra travel time,” Ms Hilliard says.
She says while the two-night closure and detours will cause delays for drivers, it is essential the work is done. It is about keeping a critical and heavily used transport link safe and resilient for all road users,” Ms Hilliard says.
