In 2025, Circular line north section construction entered the stage of being fully underway.  DORTS stated that the north section links important residential and industrial hubs in New Taipei City Industrial Park, Luzhou, Shilin, and Dazhi. In the future, following the completion of construction, the commute times between Taipei and New Taipei City will be significantly reduced, with the journey from New Taipei Industrial Park to Jiannan Road Station taking only 28 minutes. For the sake of information transparency and to enable citizens to stay informed about the progress of construction projects, today DORTS released the latest construction progress video which documents the current status of the construction areas in detail.    

With a total length of 14.93km, Circular line north section includes 12 underground stations and one underground depot. Among these, the north depot, which is located below Sanchong Jixian Environmental Park, is in the peak construction phase. The construction team is fully engaged in deep excavation work as well as the erection of support structures and construction of the main structure, and the overall structure of the depot is taking shape.

As for the progress of each section contract, the diaphragm wall excavation operations are ongoing for section contract CF680A (Stations Y19A, Y19B, and Y20), which traverses Wugu District and Luzhou District; furthermore, large-scale grab cranes are being utilized to carry out deep underground excavation to ensure the stability and safety of the underground station structure. Meanwhile, construction of intermediate piles and diaphragm walls is currently being carried out on Wuhua St. and Jixian Rd. for section contract CF680B (Stations Y21, Y22, and Y23), which runs between Luzhou District and Sanchong District. For section contract CF690C, which is located at the Taipei end of Chongyang Bridge, escape shaft construction is currently underway. In addition, construction work is being carried out on the intermediate piles and diaphragm walls at station Y24, which is located at Shezheng Park, Shilin District.

DORTS explained that the construction environment for Circular line north section is extremely challenging and requires transitioning from an elevated section to an underground section. The route passes through Wugong Rd. and Jixian Rd. in Luzhou District and crosses the Tamsui River to connect Shezi and Shilin District. DORTS further elaborated that in order to coordinate diaphragm wall operations, fence layout or partial lane closures will be dynamically adjusted during the construction period.

DORTS stated that in order to ensure the safety of road users, nighttime lighting and warning signs will be significantly enhanced at construction sites, and staff will be assigned to direct traffic. DORTS also expressed their sincere gratitude toward residents for their patience and cooperation during the construction period and working together to enable the engineering team to overcome the various challenges of urban excavation while striving toward the goal of completing construction.

Following the completion of construction, Circular line north section will be closely integrated with the existing MRT network. Passengers will be able to transfer to the Taoyuan Airport MRT at Station Y19, transfer to the Zhonghe-Xinlu line at Station Y21, transfer to the Tamsui-Xinyi line at Station Y26, and transfer to the Wenhu line at Station Y29. These new transfer points will have the effect of diverting traffic and effectively alleviate congestion at downtown transfer points. 

DORTS emphasized that they will remain its original mission of serving the public in accordance with the principle of ensuring project quality and construction safety and complete this ring-shaped transportation route connecting Taipei and New Taipei City as soon as possible.
