All 5 TBMs for the project have been launched and are excavating the mainline and reception tunnels. The single-span replacement POB along Woodlands Avenue 2 was launched on February 5. The old bridge will be demolished and have its piles removed ahead of the relaunch of TBM S-893 for the RT3 drive at the end of the year.
