A concept illustration of the raised London Circuit and Commonwealth Avenue intersection.
15 May 2023
Construction is ramping up on the largest transport infrastructure project in Canberra’s history.
From Monday 15 May, trucks carrying fill will start arriving on site. This fill will be used to build the new side track that will allow motorists to continue using Commonwealth Avenue while work progresses on raising London Circuit.
Around 60,000 cubic metres of material will be required to create a level intersection between Commonwealth Avenue and London Circuit.
Raising of London Circuit by six metres to be level with Commonwealth Avenue will create a safer environment for cyclists and pedestrians, open connections between the city and the lake, and enable the extension of light rail to Commonwealth Park.
This is an important milestone for the project as it moves construction into the major earthworks stage with commencement of the side track build to enable the bridges over London Circuit to be demolished.
When the side track is completed later this year traffic will be diverted to the new road to maintain two lanes of traffic on Commonwealth Avenue in each direction.
The start of work to build the side track will involve trucks bringing in fill material from another construction site in Barton to the raising London Circuit site at both site entrances on Constitution Avenue and Edinburgh Avenue.
The fill material primarily consists of soil that will be used to raise the road before the road pavement and landscaping works are added. Before being brought onto site the fill is rigorously tested for contaminated materials and to ensure it meets engineering requirements and EPA standards.
Around 40 trucks per day are expected to bring in fill to the raising London Circuit site to build the side track. Trucks carrying fill will use arterial roads between Barton and the city to import fill from Monday to Friday, between 7am and 5pm and Saturdays between 7am and 1pm.
As large trucks start to arrive on site from next week and continue to increase throughout the project, this is a timely reminder for Canberrans to take extra care on the roads and be aware trucks have larger blind spots and require more time to stop, even at lower speeds.
