The final and semi-permanent traffic diversion stage 5 has been implemented, which sees the worksite for the basement excavation and casting works situated in the center of both carriageway following the completion of the entire station roof slab. This layout is rarely preferred as it severely limits the working space and site movement of the construction activities, however necessary as the most optimal solution so as to not disrupt access from the residential apartments and side roads along both sides of the road.
Excavation works at the station to the concourse slab is in progress with the first section of the concourse slab cast. D-walling works are in progress at entrance B. The RTBM drive is almost completed and will reach the escalator shaft wall within the next few days.
