Duplication of BR-470 Advances, Has 62 Km Delivered, But Still Needs to Complete 11 Km and Seven Viaducts While the Government Promises to Finish Everything in 2026
The duplication of BR-470 is one of the oldest and most awaited infrastructure projects in Santa Catarina. Discussed for over two decades, the highway has finally reached 85% completion, with a good portion of the sections duplicated and open to traffic.
Nevertheless, the daily reality is still harsh for those who depend on the road. The duplication of BR-470 remains unfinished, with critical bottlenecks, ongoing construction, and frequent traffic jams, especially in urban sections and access routes to Blumenau and Indaial.
Decades of Promises and a Project That Drags On
The duplication of BR-470 began to be debated in the early 2000s, but spent years in stoppages, government changes, and lack of funds. Throughout this period, the highway has solidified its status as one of the most dangerous and congested in the state.

After nearly twenty years of halted and resumed construction, the Transnordestina has reached 79% completion and finally promises to connect the hinterland to two ports on the Northeast coast.

Madrid wants to build the world’s largest Ferris wheel at 260 meters and €300 million, surpass Dubai, transform Spain’s landscape, and create its own ‘Eiffel Tower’ in a project that still faces resistance and depends on approval.

Saudi Arabia and Qatar signed the agreement to connect Riyadh to Doha with a high-speed train traveling at 300 kilometers per hour, covering 785 kilometers of desert in about two hours.

What is the ideal distance between one pillar and another? The measurement used in houses with up to 2 floors can avoid huge beams, low ceilings, and extra construction costs.
Only in recent years has the project gained more consistent momentum, allowing for the delivery of large duplicated stretches and viaducts awaited for decades.
What Has Been Delivered So Far
Currently, 62 km of the duplication of BR-470 are already completed and open, out of a total of 73 km planned between Navegantes and Indaial. Of the 27 viaducts planned, 20 have already been delivered and are in operation.
Only this year, important structures have been released, improving flow at critical points and reducing accidents in areas previously considered dangerous.
What Is Still Needed to Complete the Duplication of BR-470
Despite the progress, the duplication of BR-470 still needs to overcome its most complex sections. There are 11 km left to duplicate, concentrated mainly between Blumenau and Indaial, a region considered the biggest bottleneck of the highway.
Additionally, seven viaducts still need to be completed, including strategic works in urban accesses that currently experience queues, delays, and traffic conflicts.
Removal of the Gas Network Delayed Work
One of the main factors for the recent delays in the duplication of BR-470 was the need for removal and relocation of the natural gas network in some sections. Contractual issues and the bankruptcy of a company responsible for the service directly impacted the schedule.
Part of this issue has already been resolved, but about three kilometers remain where the relocation needs to be completed, which prevents the full progress of construction fronts.
Traffic Remains Chaotic at Construction Sites
Even with 85% completed, those who travel daily on the duplication of BR-470 still face long queues, traffic alternating between stop-and-go, and constant delays. In some viaducts under construction, drivers report intense congestion even outside peak hours.
Frustration grows when there are few or no visible workers in certain sections, reinforcing the feeling that the project could advance more quickly.
Government Promises Total Delivery in 2026
The federal government states that the duplication of BR-470 will be fully completed in 2026, ending a saga that has crossed different administrations. The promise includes the delivery of the remaining kilometers and the seven viaducts still pending.
The statement rekindles hope among residents, business owners, and truck drivers, but also generates skepticism, considering the history of missed deadlines over the past decades.
Strategic Importance for Santa Catarina
The duplication of BR-470 is vital for the state’s economy. The highway connects the coast to the Itajaí Valley and the western region of Santa Catarina, being fundamental for cargo transport, tourism, and daily commuting for thousands of people.
With the project completed, it is expected to reduce accidents, improve flow, and yield direct benefits for regional logistics, which is currently severely impacted by existing bottlenecks.
Expectations Rise, But Caution Remains
After so many delays, the completion of the duplication of BR-470 has ceased to be just a project and has become a symbol of weariness for the population. The recent progress is real, but the final stretch concentrates the toughest challenges.
While total delivery does not happen, daily life remains marked by patience, traffic congestion, and uncertainty as to whether 2026 will indeed be the year of the end of this wait.
Do you believe that the duplication of BR-470 will finally be completed in 2026 or will the history of delays continue to weigh against this promise?
Não vai ficar pronta em 2026, mas em 2027 acredito que termina, mas a 280 está muuuuuito atrasada e está também é de vital importância para SC.
A 470 não termina em Indaial onde a duplicação termina ela termina no RS e o certo é duplicar toda não só um pedaço, quem sabe até 2080 está pronta
Já viste a situação da BR 285 que liga o Oeste do RS (em São Borja) com a 101 em SC? Passa por Ijuí, Carazinho, Passo Fundo, Vacaria e possui conexão com a 470 em Lagoa Vermelha. É trecho de cargas pesadas e está entre as piores estradas que já dirigi facilmente. Muito fácil de furar um pneu, arrebentar uma bucha de amortecedor e entortar a roda.
Precisa pedir pra asfaltar a rodovia 350 caramba de rio do campo ate a 116 40 km de chao é um vergonha
Vai atrasar com certeza.
