Overview of CPE stations as at April 2026. |
We're beginning the April snapshots with a recap of the Cross Island Line's Punggol Extension (CPE) where things are beginning to ramp up as tunneling works for the entire length of the phase commence. Station works have also progressed at the three station sites under this phase of the line. Find out more as we cover the brief summary of progress made at each station site.

Overview of CRL2 stations CR19 - CR15 & contract CR210 & CR207 sites as at March 2026. |
Phase 2 of the Cross Island Line (CRL) is fast approaching road diversion season. In fact, this section of the line may have already crossed the threshold into the road diversion territory, with the first major diversion having taken place at the Maju station site. Nonetheless, other sites are likewise gearing up for their diversion-eras as well. Which sites are these and which roads will be diverted? Find out all that & more after the jump!
We have just learnt that tunneling works for contract CR106, responsible for the construction of Loyang station and connecting tunnels to Pasir Ris East station, have been completed. The westbound (WB) tunnel boring machine (TBM) successfully docked with the Loyang station box earlier this month. This follows the earlier docking of the eastbound (EB) TBM in January this year. With the latest completion, approximately 16 of the 29 tunnel drives for phase 1 have now been completed.

Overview of CRL1 stations CR2 - CR5, CR8 - CR10 & CPE station CP4 as at February 2026. |
It's been a while since we've had a Snapshot update for the Cross Island Line (CRL). Here's one from February 2026, covering several of the sites across Phase 1 and Punggol station along the Punggol Extension. How have works progressed, especially at the line's eastern end? We find out all that and more in this update after the jump.

| Graphical representation of tunneling progress for contract CR117. Based on compilation of available information and may not be the most accurate nor up to date. |
Contract CR117 has been one of the more elusive contracts to track progress of, mainly due to the different geology at the location which necessitated different construction methods. For instance, the earth retaining & stabilising structure (ERSS) employed at the site uses bore piles instead of diaphragm walls. Similarly, it has been a little difficult to track the progress of tunneling works. Nonetheless, we've managed to probe a bit more and finally have some idea of the progress when it comes to tunneling.

Another tunnel that has recently been completed along the Cross Island Line's (CRL) phase 1 section is the eastbound tunnel under contract CR106. This contract will be responsible for the construction of Loyang station and tunnels connecting to neighbouring Pasir Ris East station. Two tunnel boring machines (TBMs) are being used for the construction of the tunnels, with the launch shaft constructed under contract CR107, next to the Pasir Ris East station before being handed over to contract CR106.
