Chaytor Street retaining wall

We are strengthening the Chaytor Street retaining wall to make it safer and more resilient.

Retaining wall on Chaytor Street.

Work in 2011 assessed the vulnerability of the Chaytor Street wall and the need for strengthening work if a major earthquake were to happen. 

The wall holds up the streets above, which are Raroa Crescent and Northland Tunnel Road. It supports the area to provide for the major transport route into the city for Karori, Wilton and Northland residents.

About the project

The strengthening of the wall will consist of two phases.

Phase 1: Drilling and ground investigation work

This phase is planned to take six days from 2-7 March 2020.

There will be traffic delays during this time along Chaytor Street as the bus lane will be partly closed, and there will be no on street parking opposite the worksite. There will also be some delays on Raroa Crescent intersection with Northland tunnel road.

Please allow extra time for your journey into the city for the duration of this work.

We encourage Karori residents to take public transport where they can and also to use Birdwood Street as an alternative route for their journey to minimise disruption. We appreciate your patience during this time.

Phase 2: Wall strengthening work

This phase is planned to commence September 2020 and construction is expected to take 12 -14 months.

The second and major part of this project will include strengthening the 222-metre long wall.

Background

Wellington City Council has an ongoing programme to strengthen its major transport structure assets such as retaining walls, tunnels and bridges around the city to make Wellington more resilient in an earthquake.
