The Bangalore Metro Rail Corporation Ltd (BMRCL) on Thursday cast the first set of U-girders, a technology being introduced in the city for the first time to build Metro viaducts.
The U-girder will be stitched together to construct an elevated metro corridor along the Outer Ring Road and link it to the Kempegowda International Airport (56 km). Instead of stitching together multiple spans between two pillars, the BMRCL will erect a single-span U-girder of 28 metres in the same space. This technology is expected to complete construction at a much faster pace as compared to a segmental girder of the same length.
