御坂サイフォン橋

The Misaka Siphon Bridge is a water conveyance structure spanning approximately 750 meters, featuring two parallel stone arches positioned side by side. The construction links two banks to carry water across a deep valley.

A British engineer designed this structure in 1887, and construction work concluded after four years. The project embodied water management practices of the late 1800s.

The bridge demonstrates how water management has shaped this region for over a century and is recognized by engineers as a significant landmark of hydraulic engineering. Visitors can observe how the parallel arches define the landscape and embody early civil engineering achievements.

The structure sits within a valley and is visible from a distance, but best appreciated from specific vantage points. It is advisable to visit on clear days when the forms are easy to observe.

The system uses siphon principles where gravity pulls water down and up through the bridge to maintain flow across the valley. This physical method of water movement was a remarkable achievement at the time of construction.
