[Explore] Thu Thiem Tunnel: A Comprehensive A-Z Guide with Local Trips

At Local Trips, we understand that many readers still have questions about one of Ho Chi Minh City's iconic structures – the Thu Thiem Tunnel. The tunnel is not only a vital traffic artery but also holds fascinating stories about engineering, planning, and the development of Saigon. This article will serve as a comprehensive guide to answer all your questions, from its formation history and unique structure to practical tips for traveling through the tunnel, all compiled from the perspective and experience of the Local Trips Team.

What is Thu Thiem Tunnel? An Overview of Saigon's Project of the Century

The Thu Thiem Tunnel, also known as the Saigon River Tunnel, is Vietnam's first and most modern cross-river traffic project, connecting District 1 (the historical city center) with the Thu Thiem New Urban Area (Thu Duc City). With its strategic location under the Saigon River, the Thu Thiem Tunnel plays an indispensable role in connecting the two banks of the river, promoting the urban and economic development of Ho Chi Minh City.

History of formation and development

From Local Trips' experience, we have witnessed the incredible transformation of this area through various construction phases. Construction began on January 31, 2005, and the tunnel officially opened to traffic on November 20, 2011. The Thu Thiem Tunnel is the result of over 6 years of diligent work, utilizing advanced immersed tunnel technology from Japan. This marked a significant milestone, signifying a leap forward in Vietnam's transportation infrastructure.

Important role and significance for Ho Chi Minh City and the region

For Local Trips Company, the Thu Thiem Tunnel is not just a traffic infrastructure project but also a symbol of the city's dynamic development. Before the tunnel, traveling between the city center and the Thu Thiem area was difficult, relying on the Saigon Bridge and ferries. The Thu Thiem Tunnel eliminated this geographical barrier, significantly shortening travel time, reducing traffic congestion, and opening the door for the strong development of the Thu Thiem New Urban Area – one of Southeast Asia's most modern and promising urban areas. It is an integral part of the East-West Avenue, forming the city's backbone transportation axis.

Unique Structure and Technology of Thu Thiem Tunnel

As a company specializing in local tourism and exploration, Local Trips Company always has an in-depth view of architectural and infrastructure projects. The Thu Thiem Tunnel stands out with its unique structure and construction technology, making it a source of pride for Vietnam's engineering sector.

Tunnel design (immersed section, cut-and-cover section, approach tunnel sections)

The Thu Thiem Tunnel has a total length of 1,490m, comprising three main sections:

• Vo Van Kiet approach tunnel, District 1: 585m long, this is the approach road to the tunnel from the city center.
• Thu Thiem New Urban Area approach tunnel, Thu Duc City: 535m long, this is the exit road from the tunnel towards Thu Thiem.
• Immersed tunnel under the river: 370m long, this is the core part of the tunnel, consisting of 4 gigantic pre-cast tunnel elements sunk into the Saigon River. Each tunnel element weighs up to 27,000 tons, equivalent to a 25-story building.

The tunnel is designed with 6 lanes (3 lanes in each direction) and has a width of 33.3m, with a clear height of 8.9m. The maximum slope of the tunnel is 4%, ensuring safety for vehicles.

Internal systems (lighting, ventilation, fire fighting)

The Local Trips Team had the opportunity to learn extensively about these systems and was impressed by their complexity and efficiency. Inside the tunnel, a modern lighting system ensures clear visibility for drivers. The ventilation system operates continuously to maintain air quality, removing vehicle exhaust. Notably, the automatic fire fighting system, with 49 surveillance cameras and 37 emergency exits, is meticulously arranged, ready to respond to any emergency, ensuring maximum safety for commuters. The annual operating cost of the tunnel amounts to tens of billions of VND, demonstrating the level of investment in safety and efficiency.

Outstanding construction technology

The Thu Thiem Tunnel is the first project in Vietnam to apply immersed tunnel technology – an advanced technique globally. Reinforced concrete tunnel elements are pre-cast in a casting basin in Nhon Trach (Dong Nai), then towed to the construction site and precisely sunk into the Saigon River. We believe that thanks to these advanced technologies, the Thu Thiem Tunnel can stand strong over time, with a design life of up to 100 years and the ability to withstand earthquakes up to magnitude 7.
