U-Trough Girder
With its capability of reducing installation time, one U-Girder can be installed within a day and comes with an integrated design alongside a built-in noise barrier to ensure minimal disruption to the surrounding areas.
As of April 2023, there are a total of 2,040 U-trough girders throughout the LRT3 line which have been cast and installed by MRCB.

Segmental Box Girder
The Segmental Box Girder (SBG) is not an efficient structure. The structure is generally heavy with slower construction speed as compared to the U-Girder. Installation time per segment can take up to 3 days.
