Gunsan Geumgang Estuary Bank (금강하구둑(군산))

Geumgang Estuary Bank was completed in 1990 as part of an agricultural development project for 6 cities and counties in Chungcheongnam-do and Jeollabuk-do. The Korea Agricultural and Rural Infrastructure Corporation invested approximately 100 billion won for the project and the construction lasted for 8 years. The estuary bank can hold up to 130 million tons of water. The 1,840-meter long bank serves a bridge that connects Chungcheongnam-do to Jeollabuk-do.

Aside from being the source of water for agricultural and industrial use in Jeollabuk-do and Chungcheongnam-do, the bank also provides flood control for the area around Geumgang River. It helps keep Gunsanhang Port operational by preventing soil and sand from accumulating at the mouth of the river. It also prevents the backwash of seawater from causing damage to farmlands. Geumgang Estuary Bank has an important role as a tourist destination by connecting Gunsan and Janghang.
