The Pitan Bridge is one of the major structures of the Northern Taiwan Second Freeway which crosses Hsintien Creek in the scenic Pitan Area located 15-km south of Taipei City. A portion of the construction funding was allocated to attract an environmentally compatible design that is pleasing to both residents of and visitors to the area. The two parallel structures, each approximately 800-m in length, are on a 750-m radius curve. The 16.36-m wide single-cell box girders used on both structures are built with cast-in-place, prestressed concrete. The arching parallel structures give a simple, graceful appearance. T.Y. Lin International (TYLI) is the engineer of record.

• Kwong Cheng, current OPAC principal, served as Project Manager and Lead Engineer while at TYLI, and directed a team of engineers to perform the design and to prepare contract documents. He established the segmental erection sequence for the bridge superstructure, including segment-by-segment erection of form travelers, placement of concrete, stressing of tendons, and moving of formwork. Based on this sequence, he developed a time-dependent erection sequence computer model in the SFRAME/S3D computer program, to track each construction stage and time dependent behavior through expected service life. This modeling provided camber charts and tendon stressing specifications for use by the contractor. He also provided training to the owner's site engineer and met with the contractor to resolve construction issues throughout the construction phase.
