Vietnam's largest undersea road tunnel has an estimated total investment of approximately 10,000 billion VND.
The Cua Luc Bay road tunnel will be a landmark project for Quang Ninh province, with an estimated total investment of approximately 10,000 billion VND. According to the plan, the project will be implemented between 2025 and 2030.
In partnership with Pacific Group
On July 10th, the leaders of Quang Ninh province held a meeting with the Pacific Construction Group (China) regarding this project. The group proposed preparing a pre-feasibility study report and also suggested investment options in the form of a public-private partnership (PPP) or BT (build-transfer).

Mr. Nghiem Gioi Hoa, the founder of the group, affirmed that Quang Ninh is a key area for investment in the coming time. The group has also opened a representative office there to expedite the procedures.
The leaders of Quang Ninh province highly appreciated the interest of Pacific Construction Group and committed to creating all favorable conditions for the investment procedures to be completed quickly. The Provincial Department of Finance was assigned to act as the focal point to support the investor in the next implementation steps.
The province also expects that, with its extensive experience in urban infrastructure, the Group will conduct a comprehensive study to develop an ecological, smart, and modern urban area in the northern part of Cua Luc Bay, contributing to creating new development momentum for Quang Ninh.

Project design and schedule
According to the design, the Cua Luc Bay tunnel will run parallel to the Bai Chay Bridge, with 6 lanes and a total length of approximately 2,750m. The main tunnel section is about 2,140m long, comprising 1,000m of submerged tunnel and 1,140m of approach tunnel. The tunnel is located on the seabed at a depth of no more than 17m, is capable of withstanding earthquakes of magnitude 6 on the Richter scale, and allows vehicles to travel at a maximum speed of 60km/h.
Previously, Quang Ninh province had planned to start construction on the project in 2019 and complete it in 2025. However, due to prioritizing resources for other projects, the province temporarily suspended implementation. Subsequently, the province requested permission to self-finance the project, which was approved by the Prime Minister.

Introduction to Pacific Group
Pacific Construction Group was founded in 1995 by Mr. Nghiêm Giới Hòa. It is one of the largest privately owned construction groups in China, operating in infrastructure, transportation engineering, and architecture. The group is currently among the top 100 global enterprises and has over 500 subsidiaries and 100 international investment companies.

As of 2023, the Group achieved revenue of nearly $80 billion and operates approximately 3,000 industrial parks and urban areas across China. In recent years, the Group has accelerated its international expansion, particularly in ASEAN, Central Asia, and Eastern Europe, with numerous large-scale projects such as subway and high-speed rail lines.
In Vietnam, the Group opened a representative office in April 2019 and established Pacific Vietnam Construction Co., Ltd. with a registered capital of US$500 million. Over the past period, the Group has worked with many provinces and cities such as Bac Ninh, Lao Cai, and Lang Son to seek investment opportunities in areas such as transportation infrastructure, logistics, and industrial parks.
In May, the Group was also one of six members of the consortium that won the EPC contract for the construction of the Tu Lien Bridge and its approach roads, including surveying and building information modeling (BIM). This is considered a concrete step in the Group's long-term presence and investment in the Vietnamese market.
