EA Event (Webinar): Future Proofing and Unlocking Auckland’s Rail Network – City Rail Link Project Update

October 8, 2020 @ 4:00 pm - 5:30 pm UTC+10

This webinar will provide an overview of the City Rail Link Project, Auckland, New Zealand.  Presenters will discuss the overall project outline and key challenges, as well as a project update on the design and construction of the 3.45 km twin tunnel underground rail scheme.

The City Rail Link (CRL) Project is a 3.45km twin-tunnel underground rail link allows the Auckland rail network to at least double rail capacity. The detailed design and construction contract C3 commenced in 2019. The C3 Contract comprises two new underground stations, a redeveloped surface station, two bored running tunnels and two mined junction caverns. Nearly 1.5 years into the Alliance Contract, a project update on the detailed design and construction of the underground works is presented.
