The CRL is due for completion in 2023.
Construction for Contract 1 and Contract 2 has started.
This involves firstly constructing a new temporary entrance facility for Britomart Station in Commerce Street so the Queen Street entrance could close. This happened in January 2017.
This enables our construction partner Downer Soletanche Bachy Joint Venture (DSB JV) to build the train tunnels under the Chief Post Office and Lower Queen Street.
- the cut and cover tunnels up Albert Street from Customs Street to Wyndham Street
- the pipe-jacking of a new stormwater pipe from Swanson to Wellesley Streets
- the strengthening of the Orakei main sewer.
These are being delivered by our construction partner, Connectus.
The cut and cover tunnels - built in trenches from the surface - will be completed by late 2019.
Once the trenches have been dug, the concrete floor, walls and roof of the tunnels will be cast before the structures are backfilled.
