Overview of CRL stations and contracts as at August 2026. |
Just a quick update for August, as time really does not seem to be on our side this year. Nonetheless, we've managed to spread our coverage over the various phases of the line - a little bit here and a little bit there. In this snapshot update, we cover some of the key observations across the line from existing interchange station modification works to tunnel progress. More after the jump!

With the announcement of the Cross Island Line (CRL)'s final phase on 31 July 2026, we now know that the line will stretch for 67km, making this line the longest in the country - beating out the East-West Line (EWL)'s record of 54km by a fair bit. This means that the CRL is a really big project, spanning end-to-end across the entire country. While the EWL also crosses the island from east to west, it mostly sticks to the southern section of the island. In comparison, the CRL swings further north and south than the EWL, making its route much more varied and spread out. This translates into it being much more difficult to easily visit and keep track of all contract sites.
For this update, we tried to cover as much ground as we could to give you an idea of where the line stands in progress. As phase 3 was only announced right at the end of the month, we won't be yet including that section in this update. Nonetheless, all the previous phases of the line that were officially announced are covered in this update in some way, form or manner. There's a lot to unpack, so jump right on in after the jump.

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.

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.

Overview of CPE stations CP2 - CP4 & CRL2 stations CR16 - CR19 as at October 2025. |
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.

Roughly about three-quarters into the year, how has progress been along the Cross Island Line? We take a closer look at some of the key sites along the line in both phases 1 and 2 in this August look-back.
Beyond the upcoming road diversion mentioned in our post on the contract CR115 roadshow, several other Cross Island Line (CRL) contracts will be implementing similar diversions at their respective project sites. These changes to the road networks are scheduled to take place between mid & late August. The details after the jump.

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.

A happy new year to all our readers & followers! Recently, we have come across a few new images of tunnel boring machines (TBMs) for the Cross Island Line (CRL) phase 1. Coupled with recent deliveries to sites at Hougang, Ang Mo Kio and Defu, its definitely TBM season for the CRL. What better way to begin the new year than by taking a look at all the machines responsible for building the tunnels for the upcoming CRL1? More of them after the jump.

The weekend of 16 & 17 November will be a busy one for the Cross Island Line (CRL) with various traffic diversions, temporary road closures & changes to road schemes taking place across three different projects over 2 phases of the line. The works in particular will affect residents in Pasir Ris at the site of contract CR108, in Ang Mo Kio near site CR115 at Tavistock station and at King Albert Park at the site of CR205.

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.

The first quarter of the year has seen quite a fair bit of activity at the construction site of Pasir Ris Cross Island Line (CRL) station. Within the first three months, the alignment of Pasir Ris Drive 1 was shifted closer to Costa Ris BTO precinct, the junction of Pasir Ris Drive 1 with Pasir Ris Central & Street 51 was reconfigured and diaphragm wall works outside block 571 saw a road diversion enacted.

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.

The first few months of the year have quickly past and we're slowly getting back into the monthly routines. Here's a snapshot update of the Cross Island Line (CRL)'s various stages of construction for the month of February with work started on phase 1 and the Punggol Extension. The latest phase announced - phase 2 - has also begun early works which we also explore in this update.

| 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.
