City Rail Link C2 Tunnel Box Completion

McConnell Dowell is pleased to announce that the first 348 metres of the Auckland City Rail Link is completed. The tunnel from Wyndham Street through to Commercial Bay marks the completion of a major stage of Auckland’s new rail tunnel. 

Since December 2015, the Connectus JV has installed 362 reinforced concrete piles around the future CRL twin tunnels, relocated the major stormwater pipe on Albert Street, strengthened the Orakei sewer main at the intersection of Albert Street and Victoria Street, and relocated kilometres of stormwater, electrical, gas, sewerage, and internet lines.  

In total, 2,500 tonnes of steel bar reinforcement have been tied together, and over 10,000 cubic metres of concrete have been poured which has meant bringing in over 1,600 full concrete trucks just for the tunnel box formation. 

City Rail Link Ltd’s Chief Executive, Dr Sean Sweeney acknowledges the work of the contractors, and the support from the local community, “Construction like this in the middle of a city is never easy for anyone - the risks for workers that come from working in confined spaces, and the disruption for people living and working nearby – but we have taken a big step towards building a project that will change the way people can travel around our city.” 

The team is now nearing the completion of the removal of the temporary ground support, the relocation of the services and the completion of the backfilling of the trench.  

Starting from Wyndham Street, Albert Street will be fully reinstated starting in mid-July. The new streetscape work will head towards Customs Street block by block.  

It is intended that the first sections will be completed at the Wyndham-Albert Street intersection by the end of this year.
