Its the middle of the year and time to check in on progress made along the Jurong Region Line (JRL). Some important milestones have been made through the past month & the first half of the year, which include the completion of viaduct span construction on 80% of the phase 1 contracts and commencement of track laying works at all phase 1 temporary staging areas (TSAs). Join us for a round up of all the progress made across the line in the past month after the jump.

Viaduct span construction progress across the JRL's various contracts.

Phase 1
A significant milestone for Phase 1 of the line has been reached - viaduct construction has been completed for contracts J102, J105, J106 & J107. The only contract with viaduct construction under the first phase is the essential contract J103 though, which also includes the connections to the depot. As of June, the reception tracks had not yet be connected to the main line viaducts. In addition to viaduct construction completion, these contracts were also track-laying ready with some sections handed over to the track works contractor to proceed. Exterior fit out works have commenced at some stations, with cladding and windows being installed.

Station progress along phase 1, due in 2027, as of June 2025.

Tengah depot (Contract J101)
In a nutshell: Quiet progress was made through June, with the buildings slowly coming along. Other areas were also taking shape, with fencing being installed along the depot's test track to segregate the automated train operations from manual operations elsewhere.

21 June 2025

JS1 - Choa Chu Kang (Contract J102)
In a nutshell: Modification works continued within the existing North-South Line (NSL) station while roof truss frame installation works continued within the new JRL station. Parapet wall installation works were nearly completed, with some sections at the over run track still requiring installation. Several retail and F&B stores were now open within the existing station complex.

21 June 2025

JS5 - Corporation (Contract J103)
In a nutshell: The station has shown some progress at the exit podiums, with the structure on the northern side of the station since having more of the roof installed. Works were also progressing on the viaduct further west of the station with parapet wall installation works and viaduct deck slab casting works underway. A crossover will be installed between this station & Jurong West station, necessitating a slab on the viaduct to allow tracks from both trackways to connect with each other.

21 June 2025

JS6 - Jurong West (Contract J105)
In a nutshell: With exterior facade works having commenced some time back, the first section of external cladding was installed at the station last month. Featuring an angled design, the cladding does not sit flush against the station but undulates at right angles. Parts of the glass windows and framing were also installed beneath the completed cladding section. Work was also in progress for construction of the station's exit podiums, with the exit on the northern side further along than the two on the southern side of the station. Within the station, work had not yet commenced on the installation of the utilities boom at platform level despite roofing works having been substantially completed.

21 June 2025

JS7 - Bahar Junction (Contract J105)
In a nutshell: Where the satellite station building previously lagged behind, it has since begun to catch up with casting work taking place at the platform & trackbed levels. Work to connect the satellite station with the main station building has begun, with the installation of the first 2 pre-cast beams connecting to the transfer linkbridge. Work at the main station building was focused on internal services works and exit podium construction.

21 June 2025

JS8 - Boon Lay (Contract J106)
In a nutshell: Reinstatement works were in progress at the northern end of the contract. Preparation works were underway beneath the station for eventual road reinstatement works as well. Elsewhere along the contract's site, piers were cleaned up and sanded down to give a finished look to the line's viaduct structure.

21 June 2025

JW1 - Gek Poh (Contract J107)
In a nutshell: 5 pairs of the V-shaped columns were since installed out of a total of 7 for the full station roof frame works. The first truss that would connect the V-columns was on site, pending installation as well. Track works had recently commenced here, with parts of the track switch to the north of the station laid on the viaduct deck, pending installation. At platform level, a temporary enclosure had been installed to allow roof truss installation works to proceed concurrently while track laying works continued along the trackbed without interuption.

21 June 2025

JW2 - Tawas (Contract J107)
In a nutshell: With the roof truss frames installed, material installation works were underway for the roof system. Concurrently, installation of the station's external facade system was taking place at the platform level, with angled frames installed. Cladding or glass may be mounted within these frames subsequently. No escalators were seen to be installed at the moment.

21 June 2025

Phase 2
Works along phase 2 have been plowing along through the past month, with an additional station under contract J109 commencing roof truss frame installation works as well. Elsewhere along contract J109, viaduct span construction works were coming along with works taking place on at least 4 fronts concurrently. All stations under this phase have completed or at least commenced works on casting of the platform level structures.

Station progress along phase 2, due in 2028, as of June 2025.

JE1 - Tengah Plantation (Contract J108)
In a nutshell: With all 6 diamond-shaped columns since installed at the station, roof material installation works were underway. At the eastern end of the station, works to construct the mechanical & electrical plant room facilities were also in progress. Since last month, a new roadway was constructed next to Tengah Plantation Plaza, likely to be linked to the future exit drop off point. To the station's western end, launch gantry Magnificent Mammoth was completing a span of the Tengah-bound track viaduct. Two spans still remain for each bound to complete all viaduct construction works for this section of the contract.

22 June 2025

JE2 - Tengah Park (Contract J108)
In a nutshell: As the most completed phase 2 station currently, there does not appear to be much difference externally month-on-month. Viaducts on either side of the station also appear to be ready for the commencement of track laying works. The last remaining section of viaduct to be constructed near Bukit Batok Road also appears to have since been completed, with segments set in position via a trestle system.

22 June 2025

JE3 - Bukit Batok West (Contract J108)
In a nutshell: Akin to Tengah Plantation station, with all 6 diamond-shaped columns installed, works were progressing onto the installation of roof materials for insulation. Escalators had also notably been installed while a single span for each track remains to connect the station with the first piers to the east. Trestle structures were being built to allow for the construction of the viaduct spans.

22 June 2025

JE4 - Toh Guan (Contract J109)
In a nutshell: Due to the tight confines of the project site, this station was among one of the slowest to progress under phase 2. Nonetheless, construction works had reached the platform level with the supporting beams being worked on. On either side of the station, viaduct segment launching works were also underway above Jurong East Central.

22 June 2025

Tracks through Jurong East Integrated Transport Hub (Contract J120)
In a nutshell: Viaduct construction through the project site was almost complete, with several of the spans that were integrated with the transport hub building requiring further casting to reach the full build out design. Parapet wall installation works were slowly making progress as well.

22 June 2025

JE5 - Jurong East (Contract J110)
In a nutshell: Most of the station structure had been built to the full design height, with a few columns left to be completed at the upper platform level. To the end of the month, several major changes to the passenger circulation paths will be introduced - most notably that of the closure of the temporary staircase and lift serving Exit A of the station which lead to the former JCube mall. Commuters will instead be redirected towards new temporary staircases or escalators near Westgate mall to access the station concourse instead. These works are necessary as the concourse undergoes further reconstruction works to integrate the new transfer hub at the station's western end.

22 June 2025

JE6 - Jurong Town Hall (Contract J109)
In a nutshell: Works at the station have seen the commencement of roof truss frame installation works. The contract's launch gantry had also been busy assembling viaduct spans, with work taking place on the Tengah-bound viaduct span linking to the station building. Separately, works had also commenced on viaduct span construction near to Jurong East station using the balanced cantilevered method for the split level viaducts.

22 June 2025

JE7 - Pandan Reservoir (Contract J107)
In a nutshell: Most of the station building was undergoing platform-level casting works and covered in scaffolding for this purpose. On either side of the station, viaduct piers were being prepared for viaduct span construction works to commence. The launch gantry that had commenced works from the end of the line had since completed 16 spans of viaduct.

22 June 2025

Phase 3 (South)
The southern section of Phase 3 was making steady progress with stations at Enterprise & Tukang focusing on the construction of the platform level. Stations at Jurong Hill and Jurong Pier, though, were not in as advanced a stage of construction. This was also reflected in the progress of viaduct construction within the respective contracts.

Station progress along phase 3 (south), due in 2029, as of June 2025.

JS9 - Enterprise (Contract J111)
In a nutshell: Enterprise station was the first station along Phase 3 (South) to commence works on the platform level. These works continue on with rebar installation for the trackbed segments and casting of the structures taking place. Viaduct construction along the stretch of Jalan Boon Lay had also progressed with gaps remaining mostly where the movement & expansion joints are to be located.

22 June 2025

21 June 2025

22 June 2025

JS10 - Tukang (Contract J111)
In a nutshell: With the concourse level of Tukang station largely completed, works were focused on the construction of the platform level. Viaduct segment launching works were also commencing to the north of the station.

22 June 2025

JS11 - Jurong Hill (Contract J112)
In a nutshell: Several more station piers had since been cast, with others following suit. Launching of the precast concourse level crossheads would likely follow shortly. It is also likely that construction of the concourse slab would commence between piers where the concourse crossheads had been completed while other piers begin construction of the crossheads. Several viaduct piers had also began to pop up in the vicinity of the station. On the north side of the Ayer Rajah Expressway, viaduct span construction was in full swing. The movement & expansion joint pier constructed by neighbouring contract J111 had since been handed over to the contractor for contract J112 to facilitate viaduct span connection works.

22 June 2025

JS12 - Jurong Pier (Contract J112)
In a nutshell: Unlike other Phase 3 (South) stations, this station was being constructed on the side table of the road and featured an exit to be linked via an underground subway. Columns for the station's northern half had been cast for some time now, but works had not proceeded further up since. Additional columns were in the process of being constructed along the station's length, further south. Construction for the section's viaduct pier foundations had also recently begun with much work still ahead before the viaduct piers become visible.

22 June 2025

Phase 3 (North)
The stations and viaducts along the northern section of Phase 3 were making better progress than the southern section's contracts. Notably, all 3 stations were being built under a single contractor, allowing for easier coordination and phasing of works within Nanyang Technological University. All 3 stations were focused on the construction of the platform levels, having completed the concourse/lower concourse levels since.

Station progress along phase 3 (north), due in 2029, as of June 2025.

JW3 - Nanyang Gateway (Contract J113)
In a nutshell: Station building works are progressing with casting work for the platform level structures underway. Within this section of the project along Nanyang Avenue, several gaps remain in the viaduct at movement & expansion joint piers and along the Choa Chu Kang-bound track where piers were able to only be constructed recently.

22 June 2025

JW4 - Nanyang Crescent (Contract J113)
In a nutshell: This section of the contract, along Nanyang Drive has seen the station building come together with the lower concourse, platform and upper concourse levels almost fully constructed. Viaducts along Nanyang Drive have also made progress with approximately 2 spans remaining for completion.

22 June 2025

JW5 - Peng Kang Hill (Contract J115A)
In a nutshell: Casting works within the final civil contract are well underway for both viaduct piers and the station building structure. The station building structure has had the lower concourse level completed and the platform level in progress. Towards the northern end of the station, several taller columns were recently cast that may serve to support the upper concourse level at this end of the station. Viaduct construction work was also in full swing along both Nanyang Crescent & Nanyang Drive, with the over run track portions rising high above the surrounding buildings.

22 June 2025

Trackworks (Contract J150)
All TSA sites for phase 1 at Tengah depot, near Hong Kah station, near Forest Hill station & near Gek Poh station 1 were currently in operation supporting track laying works. Other TSA locations for further phases were not yet fully ramped up to commence works as yet.

TSA1 - Forest Hill
In a nutshell: This TSA will support trackworks from Tengah up to Choa Chu Kang. While works have commenced some time back, viaducts beyond Choa Chu Kang West station have not yet been handed over for track laying works.

21 June 2025

TSA8 - Gek Poh
In a nutshell: Recently works at this TSA ramped up to commence operations. Since then, works have commenced on track laying near Gek Poh station with the rails for the turn out being left near the location of installation. On site at the TSA, pre-assembly of rails to sleepers was underway before the entire section is subsequently lifted onto the viaduct and transported to the exact location for installation.
