Transport Minister Troy Buswell said the works marked the start of the second stage of the Perth City Link project.
‘This is an exciting day for Perth because while we are losing the 40-year-old bus station, the people of Perth are gaining one of the most technically advanced busports in the country,’ he said.
‘Putting this important piece of transport infrastructure underground will connect the Perth CBD to the heart of Northbridge.
‘When you put these works with other projects under way across the city, everyone can see that Perth is really undergoing a once in a generation era of transformation.’
The new busport is expected to cost $249 million, with funding from the State Government and the City of Perth.
