Contract CR111 for the construction of Defu station and twin bored tunnels to Hougang station recently saw the launch of its first tunnel boring machine (TBM) last month. The TBM, named Daphne, will bore the westbound tunnel of the Cross Island Line (CRL), the mobile factory assembling tunnel segments along a route of approximately 1.5km.

upcoming footpath closures in the vicinity.

The contractor for contract P105 - Woh Hup Pte Ltd - recently held a roadshow over two days at the Punggol station to inform commuters of the upcoming footpath closures. Some of these footpath closures will come in tandem with road diversions to be implemented while others will be implemented in line with phased works for the new underground station.

Tunneling work underneath Ang Mo Kio Avenue 1 for the subway connecting Exit 3 with the Teck Ghee station box was recently completed in February 2025. The contract used a Rectangular Tunnel Boring Machine (RTBM) that employed a technique similar to pipe jacking to complete the 50m long subway. This represents a significant milestone in the construction of the Cross Island Line (CRL).

Work is well underway for the construction of the Cross Island Line - Punggol Extension (CPE) which will see the line connecting Punggol and Pasir Ris stations via a branch of the Cross Island Line (CRL). Tunneling work for the majority of the alignment will be completed by a large diameter tunnel boring machine (TBM) - named Elizabeth - from a launch shaft just next to Pasir Ris Camp. Two drives will be used, one westwards ending at Punggol and a second eastwards, ending at Elias station. Before the arrival of TBM Elizabeth, ground improvement works were being carried out along Punggol Central. Diaphragm wall construction at the two station within Punggol were also well underway ahead of the TBM's arrival in a few years' time. More details on the works taking place after the jump.

As we approach the end of February, works at Hougang's North East Line (NEL) station are beginning to ramp up as it prepares for additional footfall when the Cross Island Line (CRL) connects here. Part of the initial works will see a temporary platform lift being installed to connect the platform and concourse levels. The markings for hoarding along this installation were previously laid out approximately a month ago.

It has been some time since we caught up and provided more detailed updates on the construction of some Cross Island Line (CRL) stations. We'll start off with some updates on Hougang, seeing how there has been an increase in activity over the past 2 months with the assembly and subsequent launching of the Tunnel Boring Machines (TBMs) at the station site. More details after the jump!
