Nagahama has grown to be a pivotal port town which has connected sea and river freight transport since the Edo feudal period. Traditionally ships gathered around the mouth of the Hijikawa River to load and unload their cargo. Except for temporary floating bridges which were occasionally used, boats were the only transportation method available between Nagahama Cho on the right bank and Kushu Village on the left bank of the river, and thus building a stable bridge was a long term dream for the local people.
Nagahama Ohashi was constructed as a part of a public works project to connect the Prefectural Road from Nagahama to the Kawanoishi (Yawatahama City) Line and Nagahama to the Gunchu (Iyo City) Line to help boost the economy.
The bridge was designed by Jun Masuda, who was considered to be a pioneer bridge-building consultant. He had designed many movable bridges in various styles using advanced design techniques that he had learned in the U.S. Considering such things as the number of ships passing through the river to a timber collection point upstream (an inlet of the river called Ego), geographical features, and costs, he concluded the best option would be to build a movable bridge, which opened on one side. With total construction costs of approximately 280,000 yen, (modern equivalent of approximately 2 billion yen), the bridge was completed in August, Showa 10 (1935) using the latest construction techniques. Examples of this are the construction of a foundation called caisson technique, and building techniques using floating boats and differences in tide levels.
