June was quite a significant month for the Cross Island Line (CRL)'s tunneling works. Significant progress has been made along Phase 1 and along the Punggol Extension. We take a look at the some of the contracts where tunneling works made progress in the month of June.

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 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.

| The 9 station sites of CPE & CRL2 as of end-2023. |
2023 was an eventful year for both the Cross Island Line (CRL)'s Punggol Extension (CPE) & Phase 2 (CRL2) sections with the ground breaking ceremony and contracts being awarded respectively. With the ground breaking ceremony taking place this year, work has began at all 3 station sites under the offshoot branch which connects the main CRL line at Pasir Ris with Punggol - a precursor to the long spoken about Northshore Line which would have eventually connected Punggol and Woodlands. Over at CRL2, contract awarded began, with 3 of the 9 civil contracts awarded through the year. All in all, 2023 has been exciting for the phase 2 stations.

Here's a look at the progress made at the various Cross Island Line (CRL) sites across Phases 1, 2 & the Punggol Extension in October 2023.
This morning, the Land Transport Authority (LTA) held a groundbreaking ceremony for the Cross Island Line (CRL) - Punggol Extension (CPE) section. Spanning 7.3km and adding 3 additional stations to the line, the ceremony was officiated by Acting Minister for Transport, Mr. Chee Hong Tat. Also in attendance were grassroots leaders for the various districts in which works will take place - Mr. Teo Chee Hean (Pasir Ris Elias), Ms. Yeo Wan Ling (Punggol East) & Mr. Janil Puthucheary (Punggol Central).
Today, the Land Transport Authority (LTA) released a new video showing a flythrough of Riviera station. Featuring 4 exits, Riviera station will allow tap out-transfers between the Punggol LRT East Loop and the Cross Island Line (CRL) Punggol Extension (CPE). It is interesting to note that the station will feature an upper concourse (B1), lower concourse (B2) and platform (B3) all within the paid area. The station will also feature side platforms as a result of the utilisation of a single large bored tunnel for the line from Elias to Punggol stations.

Yesterday, the Land Transport Authority (LTA), together with grassroots leaders and joint venture partner CES_SDC & Chip Eng Seng Contractors held a town hall meeting for residents at Elias Community Club to brief residents about the Elias MRT project. The guest of honour for the town hall event was MP for Pasir Ris West, Mr. Teo Chee Hean.

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.

Elias station is the sole remaining station along the Cross Island Line Punggol Extension (CPE) whose contract that has yet to be awarded. We should be able to look forward to the tender award some time this year with construction set to begin within the year as well. The station will be sited on a greenfield site bordered by Pasir Ris Drives 3 & 10 and will feature a station box with a launch and retrieval shaft on either end of the station.
