Australia’s deepest road tunnel, NorthConnex will open to motorists tonight with the final tests and safety checks being completed on the $3 billion Sydney mega project that will change the way drivers travel across the city.

Premier of New South Wales Gladys Berejiklian was joined by the Federal Minister for Federal Minister for Population, Cities and Urban Infrastructure Alan Tudge, Minister for Transport and Roads Andrew Constance, Transurban CEO Scott Charlton, local MPs and workers at the official opening event.

Prime Minister Scott Morrison said NorthConnex had delivered thousands of jobs to support hard-working families and now motorists would benefit for generations to come.

“This is one of the most significant and eagerly anticipated road infrastructure projects ever delivered in Australia,” Mr Morrison said.

Premier of New South Wales Gladys Berejiklian said the project has been a major driver of employment, creating around 8,700 jobs for the state.

“Around 300 businesses from the Western Sydney area and another 50 from the Central Coast have also contributed to the project, highlighting the opportunities this project has created for local suppliers and contractors,” Ms Berejiklian said.

Federal Minister for Population, Cities and Urban Infrastructure Alan Tudge said Sydney motorists will soon be experiencing the extraordinary benefits of the NorthConnex tunnels.

“NorthConnex is going to strip up to 5,000 trucks a day off the notorious Pennant Hills Road, which is one of the most congested roads in NSW,” Mr Tudge said.

“The safety benefits for so many families, getting people home safely at the end of each day, is immeasurable.” 

In an Australian first, NorthConnex features innovative lighting displays to help keep drivers alert, with stunning starscapes, trees and native bird highlighting the transition from the rural environment of the north to the urban environment of the city.

The Australian and NSW Governments thanked the more than 20,000 residents living along the corridor for their cooperation and patience throughout work on the project.
