What does the Ministry of Transport say about the risk of flooding on the Hoa Lien - Tuy Loan highway?
Regarding the Da Nang voters' reflection that the Hoa Lien - Tuy Loan expressway is at risk of flooding during heavy rains, the Ministry of Transport has directed relevant units to review, research, adjust and supplement the drainage system if necessary.

| Hoa Lien - Tuy Loan Expressway started construction in 2023 and is expected to be completed in 2025. |
Da Nang voters have proposed that the Ministry of Transport review and re-evaluate the drainage system at a number of major transport projects in the city. Specifically, in Hoa Vang district, there are a number of major projects being implemented such as: Expressways, National Highway 14B Renovation and Upgrade Project... Currently, the design of the drainage system from these projects has not met the requirements, leading to flooding when there is heavy rain.
Responding to the above proposal, the Ministry of Transport said that the Hoa Lien - Tuy Loan section investment project under the project to build a number of expressway sections on the North - South East route was designed to upgrade and expand the existing Hai Van - Tuy Loan route, with a total length of 11.5 km, invested by the Ho Chi Minh Road New Project Management Board. The project started in September 2023 and is expected to be completed in December 2025. The construction process encountered many difficulties and problems in site clearance.
According to the investor's report, the project passes through a relatively high terrain area, far from the Cu De River. The route intersects with water gathering streams, small streams and irrigation canals, so it is not affected by flooding from large rivers but mainly depends on the rising water level upstream of bridges and culverts when there is heavy, prolonged rain.
According to the results of hydrological surveys, through the historical floods in 2007, 2009, 2013 and 2022, the project area did not experience flooding. During the survey, design documentation, and drainage design solutions, the design consultant calculated according to the hydrological frequency, agreed upon with relevant local agencies and units1 to ensure the drainage aperture of the basin and ensure that the drainage aperture is equal to or greater than the drainage aperture according to the planning approved by the People's Committee of Da Nang City.
However, during the actual construction process, there may be localized areas of stagnant water that cannot be fully anticipated. The Ministry of Transport will direct the Ho Chi Minh Road Project Management Board to coordinate with relevant local units to continue reviewing, researching, adjusting, and supplementing the drainage system (if necessary) to avoid flooding and not affect the daily life and farming needs of local people.
The Ministry of Transport requested the People's Committee of Da Nang City to direct relevant local agencies and units to continue coordinating with the Ho Chi Minh Road Project Management Board during the review process to ensure the project is completed and investment efficiency is promoted.
In addition, the Ministry of Transport requested the People's Committee of Da Nang City to direct relevant local agencies and the Department of Transport of Da Nang to promptly review, propose adjustments and supplement the drainage system (if necessary) during the implementation of the National Highway 14B renovation and upgrading project to avoid flooding and not affect the daily life and farming needs of local people.
