The Underwater Tunnel from Itajaí to Navegantes Will Bring Significant Improvements in Urban Mobility and Property Valuation, Impacting the Entire Region.
Who would have thought that soon we could cross from Itajaí to Navegantes through an underwater tunnel? It may seem like an idea out of a science fiction movie, but this bold project is about to become a reality! The underwater tunnel from Itajaí to Navegantes is an engineering work that promises not only to ease traffic on BR-101, but also to transform mobility and property valuation in the region.
With plans in development since 2008, the construction of this underwater tunnel is a clear example of how infrastructure can change the game for an entire community, connecting people, improving transportation, and also increasing the value of nearby properties.
Project of the Underwater Tunnel from Itajaí to Navegantes
The project of the underwater tunnel from Itajaí to Navegantes is not just a major news for those living and working in the region, but also a milestone for urban planning in Santa Catarina. Architect Diego do Santos, graduated from Univali, and his team are responsible for the design of the tunnel, which will be one of the first of its kind in Brazil, facilitating traffic between the two cities without the need for bridges or ferries.

New CCR concrete paving technology promises roads up to 3x more durable, less maintenance, and cost reduction in Brazil.

Made from recycled plastic, plastic wood is gaining space in the construction industry because it does not rot, resists moisture, and reduces maintenance costs over the years.

Florianópolis will receive a million-dollar BRT that will begin construction in 2026 with nearly 400 million in funding from the federal government and the Inter-American Development Bank, and the map already shows the routes for the exclusive bus corridors.

Without a blueprint, without an engineer, and using scrap from the dump, a father spends 15 years building an 18-room castle for his daughter, featuring tram tracks, 13 fireplaces, and over 700 m², which may now be demolished.
Since its conception, the tunnel project has gone through several planning stages. ANP (National Agency of Petroleum) was fundamental in bringing together the 11 municipalities in the region to ensure that the work met urban mobility needs. The tunnel will be part of a larger project, Promob, which also includes bike lanes, 100% electric regional public transport, and leisure areas.
900 Meters Long
According to Diego, the underwater tunnel will be approximately 900 meters long, with access ramps that comply with all safety and mobility standards. “It’s not just a concrete structure, it’s a revolution in the way people will connect between the cities“, said the architect. Additionally, the construction will have a significant impact on property valuation, with green areas and community spaces planned in the project.
The Forecast is That Construction Will Begin in the Second Half of 2025
The forecast is that construction will begin in the second half of 2025, after all legislative and executive approvals are completed. The underwater tunnel is partially financed by a consortium of companies and has the support of the World Bank. Cities like Itajaí and Navegantes have already approved the project in their city councils, and the positive impact on traffic on BR-101 is one of the main arguments for its approval.
This project is compared to other underwater tunnel initiatives around the world, such as the one connecting Santos to Guarujá in Brazil and the tunnels in South Korea and Denmark. “We are following the same technical and safety standards as these countries, ensuring the quality and durability of the work“, added Diego.
Once completed, the underwater tunnel from Itajaí to Navegantes will be a game changer for the region, alleviating the intense flow of vehicles and generating new real estate investments, as well as improving the quality of life for those who travel between these cities daily.
The Underwater Tunnel from Itajaí to Navegantes is on Track to Become an Infrastructure Landmark for Santa Catarina
With the start of construction expected in 2025, the underwater tunnel from Itajaí to Navegantes is on track to become an infrastructure landmark not only for Santa Catarina, but for Brazil. The construction of this tunnel brings with it the promise of better mobility, economic development, and, of course, the enhancement of the region, creating new opportunities for residents and transforming the urban landscape between these two cities.
And, as always, Santa Catarina takes another step forward when it comes to innovation and urban development. Share your thoughts on the project.


Bom dia, eu tenho 65 anos não acredito nesta obra é mais uma chamada politica, faz muito anos onde está a via para o Porto?
Em breve??? Kkkkkkkkk
E o impacto no tráfego de navios? Terá? Ninguém falou…..
