The Eshima Ohashi Bridge in Japan has earned a spot among the world’s most remarkable structures for one striking reason: its steep design, which has made it famous as the “roller coaster bridge.”
Stretching 1.7 kilometers in length and 11.4 meters in width, the bridge connects the cities of Matsue and Sakaiminato, spanning over Lake Nakaumi. What truly makes it stand out is its steep gradient — reaching 6.1% on one side and 5.1% on the other. Its peak height of 44 meters allows large ships to pass underneath without the need for a drawbridge.
This unique design has captured the attention of tourists and media outlets across the globe. Although the slope may appear extreme, it’s mostly an optical illusion. Depending on the viewing angle, the incline can seem almost vertical. In reality, driving across the bridge poses no major challenge, and vehicles cross it daily with ease.
Construction began in 1997 and took seven years to complete, officially opening in 2004. Initially, engineers considered building a drawbridge, but they ultimately opted for a rigid structure to ensure uninterrupted traffic for both vehicles and ships.
Beyond its practical function, the Eshima Ohashi has also gained cultural significance. Its popularity soared after appearing in a Daihatsu Motor commercial, where the company showcased the durability of its Tanto minivan by testing it on the bridge’s curves and incline.
In terms of safety, the bridge has two lanes — one in each direction — and is equipped with traffic signals to prevent congestion and maintain smooth flow. Despite its intimidating appearance, there have been no major traffic issues reported.
Today, Eshima Ohashi stands not only as a vital piece of infrastructure but also as a tourist attraction and a symbol of bold, modern engineering. With its dramatic design, it continues to fascinate both locals and visitors, proving that functionality and visual impact can go hand in hand.
