The Saikaibashi ( Japanese 西海 橋 , dt. "West Sea Bridge") is an arch bridge in the urban area of Sasebo in Nagasaki Prefecture on the island of Kyūshū in Japan .

When construction began in 1951, the bridge was the third largest arch bridge in the world. It was completed in October 1955 and released the following month for use as a toll route ( 有 料 道路 橋 , yūryōdōrobashi ). Since the completion of the bridge over the Hario Strait, which connects the Ōmura with the Sasebo bay , it is the shortest connection between Sasebo and the Nishisonogi peninsula.

Building history

In 1941, the construction plan was frozen when the Second World War broke out. In June 1950 planning is resumed and the construction costs are re-calculated. Much of the funding came from the United States, which had been in charge since the occupation of Japan at the time. The groundbreaking ceremony took place in November 1951, followed by completion in October 1955.

The toll booths were opened on December 1, 1955. In 1956, the Japanese State Highway Company took over and management was turned over to the Ministry of Construction. On April 1, 1970 the national road 202 was inaugurated and from March 1, 1970 the bridge was passable without charges. The total cost of the project at the time was around ¥ 550 million .

The bridge is the symbol of the city region and is now a popular tourist destination.
