City Rail Link is New Zealand’s biggest transport infrastructure project.
The project consists of a 2.2-mile-long double-track rail tunnel underneath Auckland’s city center, between Britomart and Mount Eden or Maungawhau railway stations. It will be incorporated into Auckland Transport’s rail network.
Two new underground stations will be constructed to serve the city center: Te Waihorotiu near Aotea Square and Karanga-a-Hape near Karangahape Road.
Waitematā will be converted from a terminus station into a through station. Mount Eden station will be replaced by Maungawhau station, a new station with four platforms to interchange the new CRL line and the existing Western Line.
