The final delivery of railway tracks arrived at the Northern Tunnel Portal site in May 2022. In total, 9,570 m of railway tracks have been delivered to site and will be installed in the northern section of the Cross River Rail tunnels over the coming months.
Excavation and construction of the Northern Tunnel Portal structure is ongoing. With the gantry crane now removed, the final section of roof will be installed in June 2022.
At the Albert Street site the 50-m-deep station box has been fully excavated. It’s the deepest hole ever excavated in Brisbane, where about 47,000 m3 of spoil was removed, 340 rock anchors, over 1,500 bolts and 4,500 m3 of shotcrete were also used. Given the significant depth, 19 massive steel propping beams – each weighing about 50 tonnes – were used to ensure the excavation was stable.
At the Woolloongabba site the concrete lining works in the station’s caverns have been completed. More than 20,000 t of concrete was used to line the caverns over the past seven months. Crews will soon start fitting out the station’s mezzanine level, while escalators and lifts are due to start being installed later this year. The tunnels are also continuing to take shape, with the first section of track soon to be laid underground between Woolloongabba and Albert Street sites.
