Da'an River Railway Bridge

The Da'an River Railway Bridge is a steel structure spanning nearly 640 meters across the valley to connect both sides. Steel trusses and concrete piers form a distinctive framework visible against the landscape.

The bridge was built in 1913 during Japanese colonial rule and was one of the longest railway spans in East Asia at that time. A 1962 typhoon damaged it, after which engineers reinforced the structure with updated trusses and kept it operating until 1992.

The bridge shows how rail transport once linked this valley and shaped the region's growth. Passing trains were a sign of commerce and connection between the two sides for decades.

The bridge sits in Houli District and can be reached via local roads from Taichung City. Since it no longer carries train traffic, visitors can approach the structure closely to view its details and the surrounding landscape.

The bridge was repaired using Warren trusses, a distinctive structural pattern that significantly extended its lifespan. This repair method shows how local engineers creatively addressed damage from natural disasters.
