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

At Local Trips, we've noticed that many readers still have questions about one of Ho Chi Minh City's iconic landmarks – 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 guide to answer all your questions, from its history and unique structure to practical tips for traveling through it, all compiled from the perspective and experience of the Local Trips Team.

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

The Thu Thiem Tunnel, also known as the Saigon River Tunnel, is the first and most modern river-crossing traffic project in Vietnam, connecting District 1 (the historic city center) with the Thu Thiem New Urban Area (Thu Duc City). With its strategic location beneath 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

Based on Local Trips' experience, we have witnessed the incredible transformation of this area through each construction phase. 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 was a significant milestone, marking a leap forward in Vietnam's transportation infrastructure.

Role and significant meaning for Ho Chi Minh City and the region

For Local Trips Company, the Thu Thiem Tunnel is not just a traffic 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 challenging, relying on 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 indispensable part of the East-West Highway, forming the city's backbone traffic axis.

Unique Structure and Technology of Thu Thiem Tunnel

As a company specializing in local travel 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, a source of pride for Vietnam's engineering sector.

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

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

• Approach tunnel on Vo Van Kiet side, District 1: 585m long, this is the approach road to the tunnel from the city center.
• Approach tunnel on Thu Thiem Urban Area side, Thu Duc City: 535m long, this is the exit road from the tunnel towards Thu Thiem.
• Immersed tunnel section under the river: 370m long, this is the core part of the tunnel, consisting of 4 massive tunnel segments that were pre-fabricated and immersed into the Saigon River. Each tunnel segment 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 and a clear height of 8.9m. The maximum slope of the tunnel is 4%, ensuring safety for moving vehicles.

Internal systems (lighting, ventilation, fire protection)

The Local Trips Team had the opportunity to learn about these systems in depth and was impressed by their complexity yet effectiveness. Inside the tunnel, a modern lighting system is installed to ensure clear visibility for drivers. The ventilation system operates continuously to maintain air quality, removing exhaust gases from vehicles. Notably, the automatic fire protection system, with 49 surveillance cameras and 37 emergency exits, is tightly arranged and ready to respond to any emergency, ensuring maximum safety for road users. The annual operating cost of the tunnel amounts to tens of billions of Vietnamese dong, 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 worldwide. Reinforced concrete tunnel segments were pre-fabricated in a casting basin in Nhon Trach (Dong Nai), then towed to the construction site and precisely immersed into the Saigon River. We believe that thanks to these advanced technologies, the Thu Thiem Tunnel can remain stable over time, with a design lifespan of up to 100 years and the ability to withstand a magnitude 7 earthquake.
