Auckland’s City Rail Link has unveiled the connection of the Commercial Bay tunnels to the Albert Street tunnels today.
The $3.45 billion central city transport infrastructure project is expected to be finished in 2024.
Mayor Phil Goff says they are now one step closer to delivering Auckland's first underground rail line.
"The CRL is the most significant infrastructure project in New Zealand. When it is complete it will carry more than 50,000 passengers during peak hours and completely transform the way people move about the city.
"It will significantly enhance the efficiency of our entire public transport network, freeing-up our streets from bus congestion and delivering more efficient and frequent train services across the city," Mr Goff says.
CRL's chief executive Dr Sweeney says the nature of this project has made today's milestone even more significant.
"It’s fair to say that getting to this point has not been without its challenges. This is the largest transport project ever undertaken in New Zealand and building it within the middle of a built-up city is no small task.”
