Overview of CRL1 stations CR4 - CR5 & CR8 - CR11 as at April 2026. |
Last week, we took a look at the progress of the Cross Island Line (CRL)'s Punggol Extension. This week, we catch up on progress along CRL's phase 1 section, covering 6 contracts under the phase. Join us as we take a look at progress made from Pasir Ris East to Ang Mo Kio in this snapshot update of CRL1.

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.

It's been a while since we've done such an extensive coverage of the Cross Island Line (CRL) across its three current phases that have been announced thus far, hence we thought we'd let October be our month of diversity. Updates for this month stretch from Pasir Ris East all the way to Punggol & Jurong Lake District. If you've been curious on how things were progressing, this post is for you. Do be ready, this update's kind of MEGA.

Overview of CRL1 works under contracts CR106 - CR117 as at July 2025. |
There's a fair bit to update in this snapshot of the Cross Island Line (CRL) for July 2025. This update will mainly focus on progress along phase 1 of the line, the section with the most progress thus far due to the section's earlier announcement, contract award and commencement in general. Nonetheless, tunneling is also underway across all announced phases thus far, so we will touch a little on the progress made on that front thus far. All this & more after the jump.

It has been a while since we've done a snapshot feature of the Cross Island Line (CRL), with our last being done in February for the Punggol Extension. Part of this stems for the works being "less noticeable", since the majority of this takes place underground and relatively out of sight. Another part is that it also appears that updates on the CRL aren't as popular compared to updates on other lines (granted, the above ground line updates are A LOT more interesting as you actually see things change with most monthly updates). Nonetheless, we thought it's time to see where the CRL is in progress with this rather comprehensive mid-year update.

July was a momentous month for the Cross Island Line (CRL). All civil contracts for the construction of stations across phases 1, 2 and the Punggol extension were awarded. Along phase 1, several contracts were in the midst of Tunnel Boring Machine (TBM) assembly and subsequent launch as well. In this update, we take a brief look at the progress made across the line's first few phases.

Another week, and another month goes by. We're now clearly heading towards the middle of the year with June underway. Here's a look back at the progress made at the various Cross Island Line station sites in May 2024. There's a bit more to see now that some of the Tunnel Boring Machines are in the ground and beginning their boring journeys through the east to construction the line.

First of all, unfortunately we only managed to drop by the site towards the end of Q1, so there are somewhat fewer images in this update. However, works thus far have mostly been relegated to diaphragm wall construction for the most part and are hardly the most exciting of works. Perhaps it is not such a bad thing to have visited only once over the past quarter. Nonetheless, we'll do our best to break down how things are progressing over at the site.

We're pretty much done with April of 2024 - what a quick first third of the year it has been! Things are quickly becoming serious over along the Cross Island Line (CRL)'s first phase of 12 stations stretching from Aviation Park to Bright Hill with tunnel boring machines (TBMs) being delivered to site and lowered into launch shafts, station box excavation starting and bored piling continuing. We'll do a brief overview of the CRL1 stations as of the end of April 2024. More after the jump!

It's been a whirlwind first quarter of the year. We take the opportunity to check in on the progress of the various construction sites along the Cross Island Line (CRL)'s various phases in the month of March and provide a glimpse at the progress being made. Do check out the various projects after the jump.

| 10 stations of the Cross Island Line's phase 1 as at end-2023. Aviation Park & Defu are not represented in this post. |
Sorry this post was a little delayed - got caught up between travelling & work. But we're here and made it to 27th December after all. For this post, we're covering the 10 stations that we have the most pictures of along the Cross Island Line (CRL)'s phase 1. The 2 stations not covered in the post today are Aviation Park and Defu. We may cover them at a later time. Nonetheless, it has been an eventful year for the CRL with the groundbreaking ceremony being held in January 2023. Construction has been well under way at all sites with work in full swing for the construction of the earth retaining & stabilising structures (ERSS). Several intermediate launch shafts have been built as well and excavation commenced at a few sites in particular.
Please be fair warned that this post is a mega-post and extremely photo-heavy. It may suck up a lot of your bandwith after the jump.

Overview of CRL1 stations CR4 - CR11 & Contract CR110 as at September 2023. |
Our snapshot update for the Cross Island Line (CRL) phase 1 in the month of September 2023 is here. We have also begun the Q3 updates for some stations, so those updates will be more detailed than the ones reflected here. Nonetheless, do enjoy the brief update on the 9 contracts for September.

So we're commencing our Q3 updates slightly early with Pasir Ris East up first. Over at the eastern end of the station, works are focused on constructing the diaphragm walls for the launch shaft where tunnel boring machines (TBMs) will be lowered by neighbouring contractor Woh Hup for contract CR106. The TBMs will bore the twin tunnels eastwards, to Loyang station. As such, the launch shaft will be completed under CR107 but subsequently handed over for tunneling works. Upon the completion of tunneling works and first stage concreting, the shaft may be handed back to CR107's contractor, Singapore Engineering & Construction - Sinohydro Corporation Limited joint venture, to complete the remainder of the works.

Since you seemed to enjoy the snapshot feature on the Jurong Region Line (JRL), we'll give this a try for the Cross Island Line (CRL) as well. With time, the 3 CRL Punggol Extension (CPE) stations can also be featured together with the 6 CRL2 stations in future updates. But that is still some time away as yet. For the moment, here's the snapshot of 9 CRL1 stations as of August 2023.

| 29 August 2023 - Operating hours as displayed on the site office hoarding. |
Recently, the Cross Island Line (CRL) phase 1's Project Information Centre (PIC) has been opened to the public. Operating hours for the PIC are during weekdays during office hours. Do note that you will need to get in touch with the Public Relations Officer to secure a slot before heading down so that the PIC will be manned during your visit. Not doing so may result in disappointment should the officer be engaged and unable to open the centre for you. Nonetheless, the team paid a visit to the PIC today and are here to relay what you can find once you are there.
Telegram groups have become the new means through which the Land Transport Authority (LTA) has digitised its outreach to stakeholders with new rail projects. The messaging platform has been used as a uni-directional channel through which circulars and updates on the various construction contracts are pushed out to residents, businesses and commuters in the area where construction works are taking place. The first wide-spread adoption was undertaken by the Circle Line Stage 6 (CCL6) project and subsequently adopted by the Jurong Region Line (JRL) as well. It appears that the Cross Island Line (CRL) is using this as well. We attempt to consolidate the links for you to join the Telegram channels as well, which have been rolled out for CRL1 and CPE sections, for which all civil contracts have been awarded thus far. It is assumed that the same will follow for CRL2 once the contracts have been awarded and for CRL3 in due time as well.

Our last update for Pasir Ris East station under contract CR107 was at the end of 2022. We made a visit right at the end of Q1 2023 and are ready to present to you an update of the site. Since the road closure of a stretch of Pasir Ris Drive 1 between Pasir Ris Drives 2 and 4, work has taken over the former roadway.
Various activities are taking place along the entire stretch with the arrival of hydrofraise frames and a clam shell grabber machine to facilitate diaphragm wall works. There do not appear to be betonite slurry silos or a treatment plant on site yet, hence it is unlikely that these works will begin so soon.
Meanwhile, works for the base of the eventual 10 to 12 metre tall noise barriers can be seen. Concrete bases have been built at various locales, but the installation of the barrier has yet to begin. Photos available after the jump.
