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.

CR107 - Pasir Ris East update Q1 2024

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.

CR107 - Pasir Ris East update Q3 2023

 

17 September 2023 - An aerial view of the station work site from the eastern end.

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.

CR107 - Pasir Ris East Q1 2023 update

 

30 March 2023

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.

CRL1 Video directory

 

Yesterday, the Land Transport Authority (LTA) released a video showing a flythrough of the upcoming Tampines North station along the Cross Island Line (CRL) phase 1. LTA has been noticeably more active in uploading videos of & marketing the CRL across its social media channels. In addition to the new video on Tampines North, they also uploaded another video on the Rectangular Tunnel Boring Machine (RTBM) being used at the Teck Ghee station under contract N109A to construct subways to two exits located within Bishan-Ang Mo Kio park.

Since our last visit to Pasir Ris East following the closure of a section of Pasir Ris Drive 1 to facilitate construction works, there have not been too many changes. Work is mostly still at a site preparation phase with trees mostly still intact. The closed section of roadway has temporary metal barriers placed to keep pedestrians off the street while work goes on. Jersey barriers can be seen at the site as set up works continue.

On 30th October 2022, a section of Pasir Ris Drive 1 between the junction with Pasir Ris Drive 4/Pasir Ris Street 11 & the junction with Pasir Ris Drive 2/Pasir Ris Street 12 was closed to road traffic. The road closure will allow for the construction of the future Pasir Ris East station along the Cross Island Line (CRL). The team paid a visit a day after the closure to check out the site and see how things had changed following the road closure.

CR107 - Bus route diversions

17 October 2022 - A notice by SBS Transit on the upcoming bus
service route amendments due to the closure of Pasir Ris Drive 1.

Its about 2 weeks to go till Pasir Ris Drive 1 is closed to facilitate the construction of Pasir Ris East station on the Cross Island Line (CRL). In our previous update, we posted on the circular issued by the Land Transport Authority (LTA) but noted that there was no information as yet about the bus route diversions. SBS Transit first posted about the diversions on Monday, 17 October. This was soon followed by LTA & Go-Ahead Singapore. Do check out the poster by LTA below.

CR107 - Closing the road

Circular by LTA.

Annex A to above circular by LTA.

The first of several road closures within Pasir Ris is almost upon us. At the end of the month, a section of Pasir Ris Drive 1 between Drives 2 & 4 will be closed to road traffic to facilitate the construction of the Cross Island Line (CRL) Pasir Ris East station. In a circular to residents, the Land Transport Authority (LTA) has mentioned that the affected bus stops along Pasir Ris Drive 1 will be relocated along Pasir Ris Street 11 instead.

Pre-construction - Pasir Ris East

Pasir Ris East station will be the fourth station along the first phase of the Cross Island Line (CRL). The station will be built under Pasir Ris Drive 1, near the Pasir Ris East Community Club (CC), Pasir Ris Polyclinic and Pasir Ris Neighbourhood Police Centre (NPC) and stretches through the neighbouring housing estate to end at block 208.

CRL1 - Detailed station location maps

During the ministerial visit and announcement at Bright Hill station for Cross Island Line stage 1 (CRL1) this morning, there were no exhibits showing the detailed station location maps for each of the 12 stations along the announced section. Additionally, the Land Transport Authority does not appear to have released such maps either. Instead, we have noted various Members of Parliament have been posting these on their social media platforms. Do have a look at some of the more detailed station location plans we've found and we will continually update on any new maps as we come across them.

Edit @ 1634pm - Defu, Serangoon North & Tavistock station location maps added.

Edit @ 0953am on 26 Jan 19 - Aviation Park, Hougang, Ang Mo Kio, Teck Ghee & Bright Hill station location maps added.

CRL1 announced

The Land Transport Authority announced the station locations for Cross Island Line stage 1 (CRL1) this morning at a site visit by Transport Minister Khaw Boon Wan to Bright Hill station. This will be the location of stage 1's western terminus.

Do stay tuned as the official press release becomes available later this afternoon.

Speculated station locations

After collating all the sightings of soil investigation works, we can finally compile a list of probable station locations for the Cross Island Line eastern (CRLe) section. Knowing that the line stretches from Changi to Bright Hill, here's our list of the speculated stations.

Besides serving Punggol, the Cross Island Line (CRL) will also serve Pasir Ris. It is envisaged that Pasir Ris would see up to 3 new MRT stations serving the various neighbourhoods with new rail links. In December 2016 we noted several boreholes around Pasir Ris which are potentially related to the CRL pre-construction works. For the purpose of identifying the districts within Pasir Ris, we will refer to the sections as Elias, Pasir Ris Central and Pasir Ris East.
