Mr O’Farrell said the project will cut travel times for tens of thousands of South Western Sydney motorists every day.
“This was a key election commitment for South Western Sydney and I am delighted we are now more than halfway towards the project’s completion,” Mr O’Farrell said.
“The tens of thousands of motorists who use the M5 everyday can see the progress that’s being made and will soon benefit from the upgrade with reduced travel times.
Mr Gay said major work on the M5 West Widening project started in August last year and is on track to meet its completion date.
“Work currently under way includes road building work including asphalting in the central median area of the road.
“The next stage of work will include the removal of the existing tolling infrastructure and the continued installation of permanent electronic message signs.
“We know that more than half of eastbound motorists using the M5 West exit before King Georges Road.
“So it’s great news for these motorists that sections will be progressively opened as they are completed from the middle of next year.
“The widening is also a key project as we prepare to duplicate the tunnels and widen the M5 East which will meet the M5 West at Homebush Bay Drive as part of the WestConnex project,” Mr Gay said.
The $400 million widening project is funded by Interlink Roads with the NSW Government contributing $50 million towards the cost of noise walls and other noise mitigation measures.
The project includes six kilometres of new and 12 kilometres of heightened noise walls, bridge upgrades, a new motorway control centre at the Hammondville toll plaza, and improved travel information for motorists.
