The Ring Road 1 project (Hoang Cau – Voi Phuc section) is a Group A project with a total investment of more than VND7,210 billion (US$288 million). Construction began in June 2020 and, after multiple adjustments, is scheduled for completion in 2026. To date, site clearance covering 153,341 square meters, affecting 1,983 households in O Cho Dua, Lang, and Giang Vo wards, has been completed and handed over for construction.

The construction package for the road and two overpasses at the Lang Ha – Giang Vo intersection began on January 9, 2026. Contractors have completed demolition, site clearance, waste removal, and relocation of trees along the entire route. 

Construction progress has reached about 50 percent. Drainage systems, technical ducts, roadbeds, and relocation of power, water, and telecommunications infrastructure are being carried out in phases, including during holidays. Asphalt paving from Km2+500 to Km2+816 has been completed, and the technical route was opened to traffic before January 15, 2026.

Work on the two overpasses is also accelerating. The Lang Ha overpass has completed all six piers, reaching 50 percent of the total volume. The Nguyen Chi Thanh overpass has reached about 20 percent and is preparing for main span construction starting in June 2026. The project has fully disbursed its 2025 capital plan, reaching 100 percent, while nearly 14.5 percent of the VND600 billion (US$24 million) allocated for 2026 has been disbursed.

Hanoi Party Secretary Tran Duc Thang inspects the DT4 drainage route from Tay Ho Tay urban area to Hoang Quoc Viet Street.

The DT4 drainage route is an emergency project managed by the city's Technical Infrastructure Management Center. It includes the installation of a 530.8-meter D1000 pipeline and the construction of a 530-meter open canal combined with box culverts. The pipeline section that did not require site clearance was completed on April 15, 2026, 15 days ahead of the scheduled deadline.

The DT4 drainage route is being urgently constructed

The open canal section requires site clearance of nearly 21,820 square meters. On February 26, 2026, Nghia Do Ward handed over 15,800 square meters of agricultural land for construction. Work on the canal has reached about 65 percent completion. The investor and contractor are mobilizing maximum manpower and equipment, aiming to open the technical route to traffic before April 30, 2026, and complete railings, sidewalks, and landscaping before May 15, 2026.

Of the 40 items under three emergency orders, 36 are expected to be completed by April 25, 2026, to allow trial operation of the pumping system and technical connection. The remaining four items, including the DT4 canal, are scheduled for completion by April 30, 2026.

The Yen Nghia 1 regulating lake project in An Khanh Commune is being implemented under an emergency order, with a total investment of VND854.4 billion (US$34.2 million). The lake covers about 20 hectares and has a storage capacity of 0.5 million cubic meters. Site clearance for 23.5 hectares has been fully completed. Medium- and low-voltage power systems are being connected and are expected to be completed by April 28, 2026. 

Since late January 2026, construction has been carried out simultaneously at 15 work fronts, maintaining rapid progress and gradually forming the lake basin and embankment structures.

The project to improve the western drainage system of the city, focusing on Yen Nghia pumping station and La Khe Canal, has total investment of more than VND4,722 billion (US$189 million). The pumping station hub, including seven packages, has been completed and put into operation. Current focus is on 12 packages along La Khe Canal.

Site clearance has been largely completed in An Khanh Commune, Ha Dong Ward, and Duong Noi Ward. However, some households still need to partially demolish structures, and several power and water infrastructure points have not yet been relocated, affecting progress on roads along the canal.

All 12 canal packages have been launched, reaching 86 percent completion. Two packages are finished, four have largely completed dredging, two are accelerating, and two have had contracts terminated due to contractor underperformance. The project management board has proposed applying emergency procedures to appoint new contractors for the remaining work, focusing on prestressed concrete sheet piles and dredging.

The target is to complete canal dredging by April 30, 2026, finish bottom support beams by June 30, and complete remaining items by September 30. At the same time, flood prevention measures are being prepared to ensure effective drainage to Yen Nghia pumping station during the 2026 rainy season.

At the Ring Road 1 site, Tran Duc Thang stressed that the project is a backbone route that will ease congestion in the city center, open new development space, and connect key areas of the capital. Each day of delay means continued congestion, pollution, longer travel times, and a lower quality of life for residents.

He directed project management units, departments, and local authorities to fully review construction processes, identify bottlenecks, and set clear solutions and deadlines. The roadbed must be completed before September 2, 2026, and both overpasses finished before December 31, 2026.

He also required investors and contractors to commit in writing to timelines for key items, implement catch-up construction plans, and ensure safety and quality. The city will strengthen inspections and take firm action against units that fail to meet requirements or delay progress.

At the DT4 drainage project, Tran Duc Thang emphasized its importance for Tay Ho Tay and surrounding areas, where population density and development are increasing rapidly. Delays could lead to flooding that disrupts daily life and business activities. He required completion of the canal section by April 30, 2026, and sidewalks by May 15, 2026.

He also called for close coordination among agencies, especially utilities managing electricity, water, and telecommunications, to avoid delays caused by administrative procedures or a lack of coordination.

At Yen Nghia 1 regulating lake, he stressed that the project is not only a drainage solution but also a "green lung" and community space for tens of thousands of residents. He directed agencies to develop synchronized planning for surrounding infrastructure, including roads, greenery, lighting, and public spaces. The lake basin must be completed by April 30, 2026, and surrounding landscaping by June 30, 2026.

At La Khe Canal, he noted that the canal is both a key drainage route and a visible reflection of the local living environment. Its renovation is therefore both a technical and political task, closely linked to public trust in local authorities.

He requested Ha Dong Ward and the project management board to report on pollution sources, illegal discharges, encroachments, and violations, and to develop a clear plan for comprehensive handling. Violations must be strictly addressed.

Construction packages for canal works must be completed before April 30, 2026, to ensure stable drainage to Yen Nghia pumping station, with landscape items completed before June 30, 2026.

He emphasized that the renovation of La Khe Canal should create a clean, safe green corridor connected to surrounding roads and residential areas, helping raise property values and improve living conditions. Project timelines must be transparent and closely monitored, allowing public participation and oversight.
