Night works planned for State Highway 1 next week – Glenside/Grenada offramp to be closed

NZ Transport Agency Waka Kotahi | 11 Dec 2025 2:50pm | Wellington

Glenside and Grenada residents  will need to keep an eye on their travel plans next Tuesday night (16 December), with pavement and resurfacing work planned for the State Highway 1 Grenada/Glenside northbound offramp.

Contractors will be on the job between 10 pm and 4:30 am. The offramp will be closed to  traffic while the work is underway. This is for safety reasons, and also due to the size of the heavy machinery needed.

This is critical maintenance - road resurfacing helps prevent potholes and fixes pavement wear. It also improves road grip and skid resistance, making the highway safer for drivers.

While the offramp is closed, northbound traffic needing to access Glenside and Grenada will have to detour by heading north on State Highway 1, exiting at Tawa, and then head back south via Middleton Road (see detour map below).   

The work is scheduled at night, when traffic volumes are lower, to minimise delays for drivers. However, the detour will require additional travel time, so drivers needing to access Glenside and Grenada should allow extra time for their journey while this work is underway.

Drivers are asked to  follow all detours and traffic management controls in place while this work is underway – it is there to keep the public and road workers safe.

Works schedule and detour route

  • Tuesday 16 December, 10 pm to 4:30 am (traffic management to be set up from 7 pm)
  • Grenada/Glenside northbound offramp CLOSED
  • Detour available - north on State Highway 1, exit at Tawa,  and then south via Middleton Road

This work is weather-dependent, and schedules may change if bad weather occurs.
