Motorists travelling through Porirua and north toward Kāpiti are being warned to expect delays over the long weekend as extensive state highway roadworks continue across the Wellington region.
The New Zealand Transport Agency Waka Kotahi says works on Transmission Gully will include overnight closures, lane reductions and temporary speed limits from Friday, January 17, through Thursday, January 23. All works are weather dependent.
Drivers are urged to follow posted speed limits on newly laid chip seal to avoid damage to vehicles and to consider alternative routes where possible.
Transmission Gully night closures
Both northbound and southbound lanes on Transmission Gully will close overnight on several nights next week for chipsealing and paving.
Northbound closures will affect:
- Linden to SH58 Pāuatahanui on Tuesday and Wednesday nights, 9pm to 7am
- Linden to Paekākāriki on Thursday and Friday nights, 9pm to 7am
Southbound closures will affect:
- SH58 Pāuatahanui interchange to Linden from Monday to Wednesday nights, 9pm to 4.30am
Daytime lane closures and altered lane layouts will remain in place across several sections, including Rainbow Bridge, Battle Hill and between Linden and Paekākāriki.
When Transmission Gully is open, motorists heading to Porirua, Kāpiti or further north are encouraged to use State Highway 59 to avoid the works.
Concert traffic warning
Waka Kotahi has also flagged heavy traffic on Wednesday, January 21, due to the Ed Sheeran concert at Sky Stadium.
Drivers travelling north that evening are advised to avoid Transmission Gully, use SH59 or consider public transport. Metlink will run additional train services with increased capacity after the concert.
Other Porirua and regional works
Additional state highway works affecting Porirua and nearby routes include:
- SH59 Paekākāriki: altered lane layouts during the day for a watermain upgrade
- SH59 Plimmerton and Mana: daytime southbound lane closures for Wellington Water leak repairs
- SH1 Kuku and Manakau North: overnight stop-go controls for line marking
- Ngauranga Gorge and Churton Park: overnight ramp and road closures for paving
Motorists are advised to allow extra travel time, especially during peak periods, and to check for updates before travelling.
