Nguyen Trong Dong, Standing Vice Secretary of the Hanoi Party Committee, inspects the progress of the metro line connecting Kim Ma Street to Hanoi Railway Station.
On February 27, Nguyen Trong Dong, member of the Party Central Committee, Standing Vice Secretary of the Hanoi Party Committee and Head of the Steering Committee for Site Clearance of Investment Projects in Hanoi, inspected several metro station construction sites along the Kim Ma – Hanoi Railway Station – Tran Hung Dao section.
Reporting on project progress, Nguyen Cao Minh, Director of the Hanoi Urban Railway Management Board, said the pilot urban railway project from Nhon to Hanoi Station spans 12.5 kilometers, including 8.5 kilometers elevated and 4 kilometers underground, with eight elevated stations (S1–S8) and four underground stations (S9–S12).
Total investment exceeds VND34.8 trillion (US$1.3 billion), funded by ODA loans from four donors and counterpart capital from the city, with implementation from 2009 to 2027, with the elevated section from Nhon to Cau Giay has been operational since August 8, 2024, meeting quality and safety standards and receiving positive public response.
The underground portion includes four kilometers of tunnels, four underground stations and one emergency shaft. Construction progress has reached 76.3%, broadly meeting schedule targets.
Site clearance has been largely completed. Relocation of technical infrastructure has been conducted in parallel with construction due to limited space while maintaining traffic flow. As for tunnel and station, construction remain on schedule.
TBM1 completed tunneling on December 1, 2025 and is being dismantled at Station S12 – Tran Hung Dao. TBM2 is working on the S11–S12 section and is expected to finish in March 2026.
Construction progress at underground stations is as follows: the tunnel portal area is 89.01% complete, Station S9 is 50.09%, Station S10 is 72.27%, Station S11 is 67.76% and Station S12 is 75.60% complete.
Over 90% of the tunnel length has been completed using earth pressure balance TBM technology, ensuring quality and safety.
Standing Vice Secretary of the Hanoi Party Committee Nguyen Trong Dong listens to field reports.
As of February 10, 2026, disbursement exceeded VND25 trillion ($963 million), equivalent to 72.53% of total investment.
Nguyen Van Manh, Head of Contract Package CP03, said the management board coordinated with the Hanoi Department of Construction and relevant units to reduce construction barrier areas to ease traffic while ensuring safety and project progress.
At Station S9 – Kim Ma, fencing has been shortened by about 400 meters and narrowed by 0.5–1 meter, with additional reductions near 304 Kim Ma Street.
At the Lieu Giai – Kim Ma intersection, barriers were moved inward to create a temporary 3.5-meter-wide right-turn lane, easing congestion.
At the Kim Ma – Nui Truc intersection emergency shaft, fencing was reduced by about 10 meters and the temporary connecting road was widened from 6 meters to 12 meters to improve vehicle flow.
At Station S11 – Van Mieu on Temple of Literature Street, fencing was reduced by 100 meters, expanding roadway width from 7 meters to 9 meters and 10 meters of fencing at the Temple of Literature intersection was removed to improve visibility and traffic flow.
At Station S12 – Tran Hung Dao and the depot area, fencing was narrowed by 1–2 meters to widen the roadway and decorative panels were installed to enhance the urban landscape.
After inspecting the sites and reviewing progress, Standing Vice Secretary of the Hanoi Party Committee Nguyen Trong Dong emphasized that the Nhon – Hanoi Station metro line is Hanoi's first underground metro and a key project in the capital's sustainable urban development strategy.
He acknowledged the efforts of the Urban Railway Management Board and contractors in maintaining progress while ensuring traffic organization, safety and environmental hygiene in the dense inner city.
A construction site of the project.
Highlighting Hanoi's focus on addressing five major bottlenecks, including traffic congestion, Dong urged project managers and contractors to mobilize all resources to accelerate progress through a rolling construction approach.
He required scientific and coordinated construction methods, integrated underground technical infrastructure planning and adherence to standards to ensure timely and high-quality completion.
In particular, he stressed that construction barriers should be removed promptly upon completion of each section to restore road space and reduce localized congestion around worksites.
