The Taiwan High Speed Rail project is a national project linking Taipei and Kaohsiung, the two main cities of Taiwan, via a 345 km railway system.

Obayashi Corporation constructed approximately 52 km of the Taipei end of the line, as well as Taoyuan Station in the outskirts of Taipei.

For the construction of the approximately 32 km-long elevated rail bridge section, the mammoth bridge girders were fabricated in advance in the local construction yard and transported and installed by the self-propelled gantry, achieving speedy, highly efficient and high-quality construction.
