Hitsuishijima Viaduct, Double-deck rigid frame bridge in Sakaiminato, Japan
The Hitsuishijima Viaduct is a double-deck bridge in Sakaide that carries trains on one level and cars on another. The structure uses a rigid frame design to span across the water while supporting both forms of traffic at the same time.
Construction of this bridge took place between 1997 and 2004, replacing an older structure that had severe weight restrictions for vehicles. The project marked a major step forward in improving transport connections for the region.
The bridge became famous through car commercials and social media posts that played up its steep slopes, leading people to call it the 'Roller Coaster Bridge'.
The bridge features steep slopes on both sides to allow large ships to pass beneath it. Visitors should expect these slopes to be noticeable when crossing in a car or bus.
This structure ranks among Japan's largest rigid frame bridges and is one of the three largest of its type worldwide. Its impressive height and engineering design make it a notable example of modern bridge technology.
