The Kuan-Du Bridge is one of the world's largest half-through continuous steel tied arch bridges, and crosses over the scenic Tan Shui River between Kuan-Du and Pali.
The 5-span bridge has a total length of approximately 539 meters and a width of 19 meters. The main spans include: two spans at 143 meters each; one span at 165 meters; and two approach spans of 44 meters each. The bridge foundations are caissons and steel pipes.
- The Project was erected by floating three 183-meter assemblies into place by river barge. The contractor used only two bolted field splices to tie the entire bridge together.
- This gracefully tied arch design, featuring a parabolic shape, was the first to be built of structural steel locally produced in Taiwan.
- At the time of construction, the steel alternative was selected to demonstrate the capabilities of Taiwan's new steel industry.
- The Kuan-Du Bridge received the James F. Lincoln Arc Welding Foundation Merit Award.
