The Eshima Ohashi bridge, located in Japan, is a remarkable feat of engineering and is known for its steep gradient, often referred to as the 'rollercoaster bridge.' This bridge connects Matsue in the Shimane Prefecture to Sakaiminato in the Tottori Prefecture and has become a landmark due to its daunting design, which causes many onlookers to feel anxious simply by viewing it. At an impressive cost of £119 million, the bridge was built to accommodate a far greater volume of traffic than its predecessor, a drawbridge that could only support 4,000 vehicles a day.

Constructed between 1997 and 2004, the Eshima Ohashi spans 1.1 miles and rises to a height of 147 feet above Nakaumi Lake, allowing for both road and maritime traffic. This significant height and steep angle allow larger boats to pass beneath, thereby eliminating the need for a drawbridge. The bridge's design serves the dual purpose of improving transportation within the region while addressing the safety and logistical issues associated with the old structure, which encountered considerable limitations.

With approximately 14,900 vehicles utilizing the bridge each day, it stands as a crucial connection in the area and reflects Japan's commitment to modern infrastructure. The bridge not only serves a functional purpose but has also sparked interest and fascination globally, attracting tourists and thrill-seekers, although the visual experience of its steep ascent has left some feeling overwhelmed, leading to the whimsical nickname that reflects the emotional response it elicits from viewers.
