BENGALURU: The first set of U-shaped girders, which facilitate the quicker laying of railway tracks, was cast at Doddajala yard on Saturday for one stretch of Bengaluru Metro’s Airport Line. U-girder technology facilitates speedier completion of infrastructure work and has been adopted by Bangalore Metro Rail Corporation Limited both for its Outer Ring Road Line and the K R Puram to Kempegowda International Airport Line in place of the traditional box technology.
