The new M4 tunnels will be open in Sydney from Saturday morning, cutting up to 20 minutes off a trip from Parramatta to the Sydney CBD.
A joint venture of CPB contractors, John Holland and Samsung C&T, worked with the WestConnex Delivery Authority to deliver the $3.8 billion, 5.5 kilometre twin tunnels.
“WestConnex will take up to 10,000 trucks a day off Parramatta Road, which is welcome news for anyone who sits in bumper to bumper traffic on that notoriously congested corridor,” Mr. Constance said.
Seven kilometres in length the M4 East will join the M4 widening at Homebush Bay Drive and lead into the tunnel, which has three lanes in each direction.
Major work on the tunnels and connecting motorway widening started in 2016.
The WestConnex project also includes the New M5, the M4-M5 Link and the Rozelle Interchange, connecting Sydney’s west and southwest with more than 30 kilometres of continuous motorway.
Premier Gladys Berejiklian said the new M4 Tunnels will bypass 22 sets of traffic lights from Homebush to Haberfield.
“We are now just days away from drivers benefiting from the first underground section of WestConnex,” Ms. Berejiklian said.
“This is yet another major project which will allow people to spend less time in traffic and more time doing what they want.”
