What Makes the Eshima Bridge Unique?
The Eshima Bridge is often referred to as the "Roller Coaster Bridge" due to its steep gradient, which gives the illusion of a thrill ride when viewed from certain angles. This unique feature is one of the reasons it stands out among other bridges worldwide. The gradient was designed to accommodate the height requirements for ships passing underneath while maintaining structural integrity and safety for vehicles crossing over.
How Was the Eshima Bridge Constructed?
Construction of the Eshima Bridge began in the late 1990s and was completed in 2004. The project required advanced engineering techniques to address the challenges posed by its location and design specifications. Engineers utilized a combination of steel and concrete to ensure durability and stability, while also incorporating modern technology to monitor and maintain the bridge's conditions.
What Are the Key Features of the Eshima Bridge?
The Eshima Bridge is approximately 1.7 kilometers (1.1 miles) long and features two lanes for vehicular traffic. Its most distinctive characteristic is the steep incline, with gradients reaching up to 6.1% on the Tottori side and 5.1% on the Shimane side. This design was necessary to meet the clearance requirements for maritime traffic on Lake Nakaumi.
Why Is the Eshima Bridge Important for Transportation?
The Eshima Bridge serves as a crucial transportation link between the cities of Matsue and Sakaiminato. It facilitates the movement of goods and people across the region, contributing significantly to the local economy.
