Taking the design of the wind fairing of box girders for Taoyaomen Bridge as example, to facilitate the maintenance and service of the high strength bolts for articulation inside the wind fairing of the box girders and minimize the difficulties in fabrication and installation of the wind fairing, the manhole covers for the wind fairing sections are made of HPVC engineering plastics. The paper describes the performance of the engineering plastics, problems encountered in the installation of the wind fairing and the welding procedures.
