The widened lanes stretch between Southern Cross Way and Depot Road, Deagon (northbound) and southbound between the Sandgate Road bridges and Nudgee.
According to the Queensland Government, the Gateway Motorway is a major freight route supporting south-east Queensland and the upgraded section provides a critical transport corridor for more than 83,000 vehicles daily.
Queensland Minister for Transport and Main Roads Mark Bailey said motorists would begin to see the benefits of the project as peak hour traffic on the motorway though Nudgee became less congested.
“The newly opened stretch will be temporarily posted at 80 kilometres an hour while final works are completed progressively into early next year, after which time the speed limit will be raised,” Mr. Bailey said.
“Remaining works include the final layer of asphalt being placed along the motorway between Deagon and Bracken Ridge, new line marking and signage, and installation of Intelligent Transport Systems.”
