On September 29, 2026, in Dai Phuoc commune, Dong Nai city, two consortiums of investors and two project enterprises, in coordination with the Dong Nai City government, held a groundbreaking ceremony to officially activate the construction of Component 2 of the Cat Lai Bridge and Long Hung Bridge (Dong Nai 2 Bridge) projects under the public-private partnership (PPP) model.
These two strategic transportation infrastructure projects are expected to enhance connectivity between Ho Chi Minh City and Dong Nai Province, complete the inter-regional transportation network, and expand urban, industrial, and logistics development spaces associated with Long Thanh International Airport.
Not only are the Cat Lai and Long Hung bridges large in scale, but they also present unique technical and construction organization requirements, ranging from structural and foundation solutions to wind impact control and ensuring architectural value during construction. These are also the aspects that CC1 and related parties focused on researching and preparing before entering the implementation phase.
Two projects, two unique engineering challenges.
The Cat Lai Bridge has a total length of over 11.6 km, of which the main bridge and approach bridges are approximately 3.65 km long. The main bridge is designed as a cable-stayed structure with two planes of cables, a main span of 450 m, and a clearance of 55 m for navigation, meeting the requirements for container ships with a deadweight capacity of up to 60,000 DWT. The project utilizes a composite steel girder solution to withstand dynamic wind conditions along with ultra-deep pile foundations under complex geological conditions, requiring strict control over the structure, foundations, and construction organization on a high-traffic waterway.
It is known that the Cat Lai Bridge construction project is being implemented by a consortium of investors including Construction Corporation No. 1 – JSC (CC1), CC1 Asset Management and Services Company Limited, and CC1 Investment Joint Stock Company. In January 2026, CC1 Cat Lai Company Limited was established as the project enterprise, directly organizing, managing, and implementing the Cat Lai Bridge construction project.
Meanwhile, the Long Hung Bridge construction project is being implemented by a consortium of investors including Construction Corporation No. 1 – JSC (CC1), CC1 Investment Joint Stock Company, and Southern Infrastructure and Energy Joint Stock Company. CC1 Long Hung Company Limited is the project enterprise, directly organizing, managing, and implementing the project.
The Long Hung Bridge is a special-grade transportation project with a total length of 3,513 meters and a bridge deck width of 37 meters, comprising 6 lanes for motorized vehicles and 2 lanes for mixed traffic. The main bridge utilizes a single-plane cable-stayed structure, with a main span of 350 meters and bridge towers 175 meters high. This structural design requires high demands on torsional and load-bearing calculations, as well as cantilever construction techniques across a wide cross-section. Upon completion, Long Hung will be the widest single-plane cable-stayed bridge in Vietnam.
Mr. Nguyen Van Thanh – Director of Construction and Installation at CC1, representing the construction contractor, stated: “These two bridges are not only large-scale projects, but also two construction challenges with very different and complex technical requirements.” According to him, CC1 has collaborated with qualified consultants, experts, and partners to review construction conditions, safety requirements, quality standards, and finalize suitable solutions for each project.
To proactively control risks, the parties collaborated with international consultants to conduct wind tunnel modeling experiments at reputable laboratories in the United States and Denmark, assessing the impact of wind during both the construction and operation phases. The results showed that both structures remained stable under wind impact, meeting safety requirements during construction and operation.
Mr. Hoang Nhut Hai – General Director of CC1 Cat Lai Co., Ltd., representing the project enterprise, shared: “The Cat Lai Bridge is a large-scale project requiring high standards in construction organization and technical solutions. The solutions have been prepared based on research and collaboration with reputable experts and consulting firms.” He also emphasized the importance of coordination between the project enterprise, relevant authorities, consulting firms, and other stakeholders during the implementation process.
Architectural design and project realization capabilities.
Beyond technical requirements, the two bridges were designed with architectural considerations to create new landmarks on the Dong Nai River. The Cat Lai Bridge embodies the concept of "Reaching New Heights," combining soft lines inspired by the river with robust, modern forms, aiming for harmony with the landscape and the local identity. The two main towers are designed in the shape of teardrops, creating a graceful architectural line and a striking landmark at the gateway connecting Ho Chi Minh City with Dong Nai City.
The Long Hung Bridge was developed based on the concept of "Aspiration to Soar High," with the image of "Two Swords United" expressed through two towers rising and converging at the top; the details of Bien Hoa ceramic reliefs combined with the artistic LED lighting system contribute to creating a unique impression for the structure.
Mr. Nguyen Van Tuan – General Director of CC1 Long Hung Co., Ltd., representing the project enterprise, stated: “Long Hung is not only a project with complex technical requirements but also possesses high aesthetic, architectural, and landscape value, aiming to become an infrastructure highlight and a symbol of the locality.” The project enterprise is determined to focus resources, equipment, and personnel, while strengthening coordination with relevant agencies, consultants, and contractors to ensure quality, safety, and progress of implementation.
To ensure these requirements are met, CC1 has proactively prepared financial resources, human resources, machinery, equipment, and construction organization plans for each phase. With experience participating in many river crossing bridge projects such as Thu Thiem Bridge, Dong Nai New Bridge, An Hao Bridge, Rach Mieu 2 Bridge, Dai Ngai Bridge, and Van Uc Bridge, CC1 has a practical foundation to develop its management, coordination, and implementation capabilities for items requiring high technical standards.
From a management perspective, Comrade Tran Trong Thuy – Deputy Director of the Dong Nai City Police Department, and concurrently Director of the Dong Nai City Traffic Construction Investment Project Management Board, emphasized: “With large scale, high technical requirements, and complex construction conditions, the implementation of the two projects requires close, synchronized coordination and high responsibility from all participating parties.” The Project Management Board will coordinate with relevant agencies, localities, and units to overcome difficulties, especially in land clearance and handover, creating conditions for continuous construction, ensuring progress, quality, and safety.
The Cat Lai Bridge project has a revised total investment of over 24,000 billion VND, of which Component Project 2, including the main bridge and approach bridges, is implemented under the PPP method with a total investment of approximately 15,000 billion VND. The Long Hung Bridge project has a revised total investment of over 12,700 billion VND. Both projects are expected to commence construction in 2026 and be completed in 2029.
The groundbreaking ceremony marks the transition to the realization phase of the prepared design and construction solutions. With the coordination of the Investor Consortium, the Project Enterprise, the management agency, and participating units, CC1 is committed to focusing resources, organizing safe construction, ensuring quality and progress, and contributing to the formation of valuable transportation infrastructure with both connectivity and architectural value along the Dong Nai River.
