The lower pedestrian walkway is glass-floored in certain sections, allowing visitors to see the river directly beneath their feet.
The bridge is specifically engineered to withstand the significant wind pressure common within the narrow gorge environment.
The structure functions as a dual-layer transit system, separating motorized traffic from foot traffic entirely.
It is positioned to offer a vantage point for the Tenryu Line boat tours that traverse the river below.
The design was intended to minimize the environmental footprint on the steep slopes of the Tenryu-kyo valley.
Tenryukyo-Ohashi Bridge is a two-story arch bridge spanning the Tenryu River in Iida, Nagano, integrating a vehicle road on the upper level and a pedestrian walkway on the lower level. Completed in 2019, the structure reaches a height of 80 meters above the river surface. It provides direct views into the Tenryukyo Gorge, a designated Place of Scenic Beauty. The lower pedestrian deck allows visitors to look directly down into the gorge and observe the river's winding path. It serves as a key architectural landmark connecting the Kawaji and Tatsuoka districts. The bridge is part of the San-en Nanshin Expressway project, designed to improve regional connectivity while highlighting the local topography.

Wear comfortable footwear as the walk across the bridge is approximately 280 meters long.
Check local wind conditions, as the gorge can experience strong gusts at the bridge deck level.
Bring binoculars for observing wildlife or the river boats passing through the gorge below.
Avoid walking during heavy rain or high-wind warnings when the pedestrian deck may be restricted for safety.
Open year-round, but the pedestrian walkway may close temporarily during severe weather events or maintenance.
