The duplication is expected to ease traffic congestion further for commuters travelling to Darwin’s CBD.
Construction began in June 2018 and was predicted to finish in May 2020. The project has included the construction of the Garramilla Boulevard and around one kilometre of new four lane road to connect Dinah Beach Road with Cavenagh Street.
It also included a full reconstruction of around 800 metres of Tiger Brennan Drive to provide two anes in each direction between Dinah Beach Road and Bennett Street.
The works required significant underground services, blockwork and concrete retaining walls. Ground improvement of existing mangrove mud, extensive landscaping and the installation of three traffic lights was also included.
Minister for Population, Cities and Urban Infrastructure Alan Tudge said the new duplication unlocked the potential of Darwin city.
“This is a landmark project which has supported many local jobs,” Mr. Tudge said.
“In a week’s time Territorians will be able to use this road, along with Garramilla Boulevard creating an attractive entry way into the Darwin CBD.”
The Northern Territory Minister for Infrastructure, Planning and Logistics, Eva Lawler said since the opening of Garramilla Boulevard, travelling to and from Darwin City had become a lot easier.
“I thank Territoria Civil and all the local subcontractors that have worked on this project to ensure it was completed nine months ahead of schedule – supporting more than 540 local jobs.”
The street scaping for the project was designed in the Northern Territory and installed by Territory contractors.
Lord Mayor Kon Vatskalis said the City of Darwin was proud to be a part of the Tiger Brennan Drive Duplication project.
“The project has provided a unique opportunity for all levels of government to work together and we are delighted that it has been completed and delivered to the community,” Lord Mayor Vatskalis said.
“This major road provides an attractive and important additional access route into our city that will improve access and attract more people to the city centre.”
The Australian Government committed $29.5 million to the Garramilla Boulevard and Tiger Brennan Drive Stage 3 project, with the Northern Territory Government investing $25 million and the City of Darwin a further $5 million.
