The Eshima Ohashi Bridge spans Lake Nakaumi in Japan and connects the cities of Matsue and Sakaiminato. Its high clearance is designed to allow ships to pass beneath it. A two-lane concrete highway runs along the top of the bridge, which many have dared to compare to a roller coaster due to the steep gradient at its highest point.
Features of the Eshima Ohashi Bridge
It has a slope of 6.1% 5.1% on one end and 5.1% on the other, with a height of 44 meters, a width of 11.3, and a 1.7 kilometers long, which makes him the Japan's longest rigid-frame bridge, and third in the world.
The architects believed that this type of structure was a better alternative than a drawbridge, since it has the advantage of not requiring traffic to be stopped at any time, thus ensuring that traffic flows smoothly without unnecessary delays or waiting.
The structure's steep slope has led many to compare it to a roller coaster and to describe the sensation as dizzying. However, the perception of the slope depends on the observer's point of view.
When we look at a photograph of the bridge’s elevation, we can see that it doesn’t give the exaggerated impression of a steep incline, and it resembles other bridges of this style. This is because, depending on the angle from which the bridge is viewed, the sensation of vertigo it produces may or may not be emphasized.
