Strengthening work continues on key transport route

Major strengthening work will continue on Ngaio Gorge Road next month as part of the long term project to improve resilience on this key transport route.

A new 45-metre concrete anchored wall, with a 100 year design life, will be the main feature being built opposite the area of houses numbered around 89-93 Ngaio Gorge Road, as well as new footpaths, hand rails, and landscaped grass areas.

Wellington City Council’s Portfolio Leader for Transport Strategy and Operations, Councillor Chris Calvi-Freeman, says this just the latest stage in a progression of works designed to strengthen key transport routes and structures.

“We've already done major resilience work around the city, including strengthening of tunnels, retaining walls and seawalls, and previous work on Ngaio Gorge Road to secure a viable alternative route out of the city to the north.

“This approximately $1.4 million project is part of our planned work in our Long Term Plan. We are also considering options for how best to permanently secure the slope affected by the landslides last year, but a decision is unlikely to be made on this until later this year,” adds Councillor Calvi-Freeman.
The work is programmed to start mid-February, and is estimated to take up to 26 weeks weather permitting.

Two traffic lanes will be open as usual at peak times, but traffic will be reduced to one lane around the Ngaio Gorge Road work sites between 9am and 4pm, Monday to Friday, and on Saturdays between 8am and 4pm. Temporary traffic lights and traffic management will be in place, so people driving should expect short delays during the day. Safe access for pedestrians will be provided at all times.

The earthquake strengthening of the concrete wall is being constructed by Construction Technique to a design by Opus International Consultants.
