The Atlantic Ocean Road, located on the west coast of Norway, is considered by many to be the most complex highway in the world. At just 8,3 kilometers long, this unique road not only connects the island of Averøy to the mainland, but also stands out for its stunning beauty and extreme natural challenges. Passing through an archipelago of islands and reefs, the Atlantic Ocean Road is famous for its sharp curves and bridges that seem to float over turbulent waters, making it a popular route for adventurers and tourists from all over the world.
Built along County Road 64, the world’s most complex highway passes through one of the most challenging stretches of the Norwegian coast. The Atlantic Ocean Road not only connects small islands and reefs, but is also surrounded by dramatic landscapes, with the open sea of Hustadvika to the north, known for its rough waters, and the Lauvøyfjorden fjord to the south. One of the most iconic bridges is the Storseisundet Bridge, a 260-meter curved structure that defies gravity and has become a landmark of Norway.
The idea of building the Atlantic Ocean Road arose at the beginning of the 20th century, as a safe alternative to replace the region’s complicated and dangerous sea crossings. In the 70s, local residents lobbied for a road to provide easier access, and in 1983, the Norwegian government supported the project, creating jobs and opportunities. However, building the road proved to be a real challenge, with 12 intense storms threatening the project’s stability and prolonging its construction time. In 1989, the road was finally completed, a symbol of resilience and innovation.
Engineering and infrastructure challenges of the Atlantic Ocean Highway
The construction of the world's most complex highway was marked by the preparation of the foundations, which included large blocks of rock to stabilize the islands and withstand strong ocean currents. The use of advanced pile-driving techniques was essential to ensure that the bridges could withstand strong winds and harsh sea conditions.

- No more asphalt! Federal highway abandons traditional paving and adopts concrete, which lasts twice as long as the old asphalt
- Duplication of the 'death' highway (BR) will cost R$1,75 BILLION, reduce accidents, damage the economy and generate more than 600 jobs

INDUSTRY AND TRADE – FREE MARKET
The Storseisundet Bridge, with its cantilevered structure, is a remarkable example of modern engineering, built with local materials and integrating seamlessly into the natural environment, minimizing impacts on the coastal ecosystem.
Tourism and economic impact
More than just a functional route, the Atlantic Ocean Road quickly became a tourist attraction, awarded as the “Construction of the Century” in Norway. It has infrastructure for cyclists, pedestrians and tourists, offering resting places and observation points.
The route is also a prime spot for fishing and watching seabirds, such as ospreys and puffins. The highway has played an important role in local economic development, attracting investment in cafes, viewpoints and leisure areas, especially on the island of Averøy.
Comparisons with other engineering works
The most complex highway in the world is often compared to the Overseas Highway in the United States, which connects the islands of Florida to Key West. However, despite its short length, the Atlantic Ocean Highway impresses with its complexity and the variety of bridges and curves that cross rough waters and unpredictable weather conditions, including winds and storms. This aspect makes it an even more dramatic and challenging experience for drivers and adventurers.
The Atlantic Ocean Road is a true landmark of Norwegian engineering, admired for its beauty and the complexity of its construction. The project had a total cost of around 122 million Norwegian kroner, and the toll that financed part of the work was eliminated after the debt was paid off. Today, the highway not only connects communities and facilitates transportation throughout the year, but also remains a reference in sustainable infrastructure.
