The canal running parallel to the station has been diverted and demolishment of the canal is taking place along the diverted stretch of the northbound carriageway. The 3rd traffic diversion will be fully implemented upon the completion of bored pile works at the center of the station box, following which the demolishment and backfilling of the remaining stretch of canal, together with the crucial diaphragm wall works would take place.
A heavy-duty crane is currently being assembled at the Upper Thomson Launch Shaft, awaiting the arrival and subsequent lowering of TBM 3 next Friday. TBM 1 has completed its initial drive and is transitioning to its main drive. TBM 2 is on its initial drive to Caldecott.
