In a matter of no time, we've come to the end of Q1 of 2025. Its been a while since we've covered a snapshot update due to health issues. With things now coming back on track health-wise, we resumed going out and getting some updates to cover the quickly progressing Jurong Region Line (JRL) over March. Be warned, this snapshot update is a long, lengthy and juicy one.

Phase 1
There were several major accomplishments through March in this section of the line. Contract J102 completed viaduct construction and contract J107 completed its viaduct crossing over the Pan Island Expressway (PIE) in February. With the exception of Gek Poh station, all stations along phase 1 have commenced roof frame installation in some degree.

Tengah depot (Contract J101)
In a nutshell: Major progress was observed at the administration building, rolling stock workshops and multi-story bus park this month. You can read about the progress made over Q1 in more detail here.

8 March 2025

JS1 - Choa Chu Kang (Contract J102)
In a nutshell: Roof frame installation works have been taking place for the new combined JRL and North-South Line (NSL) platform, with the frames being lifted up and then slid into position. Escalators for the new JRL platforms were also installed.

JS2 - Choa Chu Kang West (Contract J102)
In a nutshell: Roof frame installation works have begun at the station. Escalators were also installed, although only 2 out of the 3 intended for connection between concourse and platform levels have been fulfilled at this point. The pits for the third escalator remain and will likely be installed in future, where demand necessitates. Construction of the station's 2 exit structures was also quickly taking shape.

15 March 2025

JS2A - Forest Hill (Contract J102, provisional future station)
In a nutshell: The shell station structure has been completed with viaducts on either end connecting to the structure. Parapet wall, cable trough and cable rack installation works were completed as well, pending for track works to commence from the nearby Temporary Staging Area (TSA). Read more about the progress of track works thus far here.

15 March 2025

JS3 - Tengah (Contract J102)
In a nutshell: Approximately 6 frames of the roof had been installed at the station. The station is still inaccessible and shrouded by vegetation, hence, for the time being, this is the best update we can provide you with. On the viaducts, rails were being installed. You can read more about the progress of rail installation as of Q1 2025 in more detail here.

23 March 2025

JS4 - Hong Kah (Contract J103)
In a nutshell: Works on the station were progressing well, with the linkbridge to the exit across Tengah Garden Avenue making significant progress. Escalators were also installed at the station concourse for access to the platform.

Tracks between Hong Kah station, Corporation station & Tengah Depot (Contract J103)
In a nutshell: Several more viaduct piers have taken shape for the eastern reception tracks connecting the Tengah Depot and Hong Kah station, leaving the area looking somewhat like a tangled mess. Viaduct segment launching is about to begin for the eastern reception tracks. Meanwhile, viaduct segment launching over the westbound carriageway of the PIE had mostly been completed while a short gap still remained over the eastbound carriageway of the expressway. Westwards, there were still significant gaps in both the main line running to Corporation station and the western reception tracks. It is likely that viaduct construction in this section may only complete towards the end of the year.

13 March 2025

JS5 - Corporation (Contract J103)
In a nutshell: Interior fit out works were in progress as painting of the station's exterior had also begun. Work continued on the exits at the northern side of the station, which would connect to the future mobility deck to be built by Jurong Town Corporation (JTC). A third exit on the south side of the station was rapidly taking shape.

13 March 2025

16 March 2025

JS6 - Jurong West (Contract J105)
In a nutshell: Works were ongoing for the interior of the station, although unlike Corporation the service booms were not yet installed. On the eastern end, works for the assembly of the trestle system to launch the remaining segmental box girders for the viaduct were ongoing. Also in progress was the construction of the station exits.

13 March 2025

16 March 2025

JS7 - Bahar Junction (Contract J105)
In a nutshell: Main station building - Escalators had been installed and the viaducts on the eastern end connecting to the station structure were launched, completing the stretch all the way to Jurong West station. At the western end of the station structure, works were underway for the casting of the second level of the transfer linkway to the Satellite station building. Parapet wall installation had begun on the Choa Chu Kang-bound track while viaduct segment launching was ongoing for the Jurong Pier-bound track.

1 March 2025

In a nutshell: Satellite station building - Casting for the concourse slab atop the two precast beams was underway. Portions of the gap between the beams were filled in towards the northern end of the station. The various columns to be cast at this level were beginning to make appearances, with the rebar bases now visible. Gaps in the viaducts remained to the south of the station and have yet to connect to the portion built by neighbouring contract J106.

1 March 2025

JS8 - Boon Lay (Contract J106)
In a nutshell: All the station's roof frames were in place. Construction of the exits on the western end of the station were taking shape rapidly. The paid transfer connection was in various phases of construction and would likely soon connect with the existing East-West Line (EWL) station structure.

13 March 2025

16 March 2025

JW1 - Gek Poh (Contract J107)
In a nutshell: Works were progressing at the platform level to complete the installation of precast beams ahead of roof frame works commencing in April 2025. Viaduct construction work continued south of the station structure, with several remaining spans to be completed.

1 March 2025

JW2 - Tawas (Contract J107)
In a nutshell: The installation of the station roof frames was about completed, with works continuing within the station for the construction of stair cases and other facilities. With the completion of the PIE crossing special span, works remained to complete the remaining sections of adjoining viaduct on the northern end.

1 March 2025

Phase 2
The next phase of the line was seeing steady progress, with viaduct construction making headway. Contract J108's stations had also all commenced on roof frame installation works while contract J109's stations had all progressed to the concourse level minimally. Work at Jurong East was also seeing swift progress, with the station expansion coming up and reaching the top levels.

JE1 - Tengah Plantation (Contract J108)
In a nutshell: The launch gantry Magnificent Mammoth had successfully crawled through the station building and had begun viaduct segment launching works in the balanced cantilevered mode across Tengah Boulevard. Subsequent updates from MPs for the newly expanded Choa Chu Kang Group Representation Constituency showed that this viaduct span was completed this month, with bonding works to follow after. There are approximately 10 spans remaining for the gantry to complete before being decommissioned. At the station itself, with the gantry having successfully passed through, roof frame installation works could proceed without interruption. All diamond columns for the station were since installed, along with the frames for both lifts at the station. Casting works for the platform slab were also in progress, previously held up by the launch gantry prior to its transit through the station.

8 March 2025

JE2 - Tengah Park (Contract J108)
In a nutshell: The last segment of the station's linkbridge connecting to an exit across Bukit Batok Road was installed this past month. With this milestone, the bridge now spans across both bounds of the major thoroughfare. Roofing works continued with the installation of the metal sheeting that would form the final weather protection layers. Work on the structure of the electrical substation that would supply traction power for the line was also substantially completed, with the supply trunking connection to the viaduct visible.

8 March 2025

18 March 2025

8 March 2025

JE3 - Bukit Batok West (Contract J108)
In a nutshell: About 60% of the diamond columns for the roof frame had been installed. At the station, the two frames for the lift shafts had also been lowered into place at platform level and the linkbridge across the PIE completely installed. To the east of the station, launch gantry Rock Steady sat 3 piers away from the station. A total of 6 spans remain to be constructed on this side of the station, with the gantry likely completing 4 of these before being dismantled. With the gantry's advancement, the pedestrian overhead bridge near the gantry's initial launching position was finally reopened after months of closure for safety reasons. To the station's west, the Tengah-bound viaduct was connected to the station building structure, leaving the West Coast-bound viaduct to follow suit. Two further gaps remained on each bound near Bukit Batok Road as these interfaced with the special span crossing there.

23 March 2025

JE4 - Toh Guan (Contract J109)
In a nutshell: With all crossheads for the station's 10 piers completely cast, precast beams were installed to support the concourse slab. Casting works for the last remaining section were in progress. Towards the station's southern end, concourse level columns were being constructed to support the beams for the platform level above. Viaduct construction was proceeding on either side of the station, with viaduct piers beginning the casting process for the crossheads. The special span crossing over the PIE was nearly complete with the curve of the viaduct making a distinctive shape when seen from above.

23 March 2025

Tracks through Jurong East Integrated Transport Hub (Contract J120)
In a nutshell: A large part of the effort through the past month has been centred on the casting of the slab that sits above the viaduct. This slab is supported by the integrated viaduct piers through portal frames as the tracks split levels to approach Jurong East station. Part of the site was being decommissioned, with turfing being laid down over the reinstated section.

23 March 2025

JE5 - Jurong East (Contract J110)
In a nutshell: Casting works were beginning for the upper platform level of the JRL section of the station while metal beams were being added to connect the new building to the existing westbound track of the EWL. It is likely that additional concrete will be poured on top of the completed metal assembly being used to replace rebar. Meanwhile, modification works to the thoroughfare for the upcoming faregate relocation were reaching completion.

16 March 2025

JE6 - Jurong Town Hall (Contract J109)
In a nutshell: The station had approached the platform level and casting work was underway for the trackbeds and parapet walls. The launch gantry had reached the final pier before the special span crossing over Jurong Town Hall Road. It is likely that following the launching of viaduct segments for the final span here, the gantry will crawl its way back towards the station to commence span construction of the other side of the station towards the Ayer Rajah Expressway (AYE). Viaduct piers on this side of the station have finally gained their crossheads and stand ready for the viaduct spans to be constructed.

23 March 2025

JE7 - Pandan Reservoir (Contract J107)
In a nutshell: Works were underway at the station's concourse level, with part of the works reaching up to the platform/trackbed level. The viaduct piers immediately south of the station had had the falsework set up to begin with installation of formwork for the crosshead. Over at the tail end of the line, the launch gantry had completed assembly of the sixth span, which would be lowered into place subsequently. Further viaduct piers towards the Pandan Reservoir station were at various stages of completion.

23 March 2025

Phase 3 (South)
Works at Phase 3's southern section had ramped up as well, with viaduct span construction making headway under contract J111. Segment launching was also underway at the northern end of contract J112, the station building structures also making some headway.

JS9 - Enterprise (Contract J111)
In a nutshell: Work had commenced on the station's concourse columns that would support the platform level. In some places, work on the beams to support the platform level had commenced. The southbound lanes of Jalan Boon Lay had also been shifted to run beneath the station. Construction of the viaducts in the vicinity of Jurong Central Park were nearing completion as the form travelers reached the end of their respective construction areas.

13 March 2025

16 March 2025

13 March 2025

JS10 - Tukang (Contract J111)
In a nutshell: Work was progressing on the construction of the concourse level beams, upon which the concourse slab would be constructed. Viaduct piers were also beginning to emerge near the station, becoming more numerous as their columns began to take shape.

16 March 2025

JS11 - Jurong Hill (Contract J112)
In a nutshell: Construction of the crossheads for the station piers was underway, with the first set being recently completed. Station and viaduct piers also began making an appearance at the northern end of the station, where they would integrate with a vehicular underpass connecting to Jalan Boon Lay across the Ayer Rajah Expressway (AYE). Viaduct segment launching was progressing slowly beyond the AYE, near the contract boundary with contract J111.

16 March 2025

JS12 - Jurong Pier (Contract J112)
In a nutshell: Parts of the station wall appear to have advanced further, although apart from the 3 columns in the station's centre, there has not been further progress with the casting of additional columns. The hydrofraise machine delivered to site does not appear to have been put to use yet, nor have works for the underground pedestrian subway begun.

16 March 2025

Phase 3 (North)
Phase 3's northern section has seen several big changes - road diversions and many more viaduct piers having their columns completed. The station building structures for all three stations were also more distinctive now, with the structures more pronounced and constantly growing.

JW3 - Nanyang Gateway (Contract J113)
In a nutshell: Nanyang Avenue was recently diverted beneath the station's completed concourse structure. This diversion would allow for works on viaduct piers supporting the Choa Chu Kang-bound track to commence construction.

16 March 2025

JW4 - Nanyang Crescent (Contract J113)
In a nutshell: Casting of the station structure for the columns and beams supporting the upper concourse was underway. At the eastern end of the station, work was progressing for the lower concourse level and supporting beams for the track bed and viaduct connection.

16 March 2025

JW5 - Peng Kang Hill (Contract J115A)
In a nutshell: Lots of casting work was underway for the station's lower concourse level, columns and beams. Further south, viaduct piers were being readied for crosshead construction as well. To the north of the station structure, viaduct segment launching was in full swing.
