Orchard Cast (II)

D-walling works for the project have been fully completed at the cut and cover tunnel ahead of schedule and excavation works have commenced there. Basement casting of the concourse slab is taking place at the station box. A major traffic realignment is being prepared at the Orchard/Paterson intersection for the underpass works.
