Myanmar Submergible Bridge Project

What is Submergible Bridge?

A submersible bridge sinks under the water when the river level rises due to flooding. Submersible bridges have been built all over the world since long ago because they are easy to build. In Japan today, ordinary bridges are built at a higher level, based on the water level that is expected to occur every few decades, while submersible bridges are built at a lower level near the water surface, making them smaller and less expensive.

Why build submergible bridges in Myanmar?

In rural Myanmar, there are many areas where streams that can be crossed on foot during the dry season become so deep during the rainy season that traffic is blocked. Bridges made of wood by the residents are washed away by the frequent floods, and daily life and economic activities are severely disrupted as people have to use boats to carry their vehicles across.
In order to quickly secure road traffic in the underdeveloped rural areas of Myanmar, JIP is working on the construction of submergible bridges and providing technical guidance to spread the technology.

Project Background

One day, a JIP member visited Myanmar on business and saw a newspaper article that said, “A river in a rural area of Myanmar overflowed and washed away a bridge for the second year in a row. More than 4,000 residents were affected, including more than 100 students who were unable to go to school.”, which launched the project.

The next year, JIP dispatched a survey team and decided to rebuild the bridges with the financial support from the Ministry of Foreign Affairs of Japan. Since then, 13 submersible bridges have been constructed in Myanmar, and two more bridges are under construction in FY2020. In order to train local engineers through the construction of submerged bridges, workshops and other events are regularly held. In recent years, JIP has also been providing technical guidance to the local government of Myanmar, which has recognized the usefulness of submerged bridges and is constructing bridges with its own budget.

FY2020Construction of 2 submergible bridges in Sagaing Region and Kayin State (funded by a grant aid from the Ministry of Foreign Affairs of Japan) ※ The one in Sagaing is incomplete and will be carried over to the next fiscal year.
FY2019Construction of 3 submergible bridges in Sagaing Region and one in Kayin State (funded by grant aid from the Ministry of Foreign Affairs of Japan)
FY2019JIP provided technical guidance to 8 submergible bridges to be constructed with its own funds by the Magway Regional Government, which recognized the usefulness of submerged bridges.
FY2018Construction of 3 submergible bridges in Magway Region (funded by grant aid from the Ministry of Foreign Affairs of Japan)
Jun 2018While many bridges were washed away in the Magway region’s first flood in decades, the submergible bridge built by JIP was undamaged.
