Introduction to U-Trough

The viaduct of the LRT3 will be constructed using the U-trough technology, a world class technology that is being utilised for the first time in a Malaysia railway project.

An integrated design, U-trough has an in-built noise barrier and a typical length of 30 metres. The use of this technology helps ensure minimal disruption to the surrounding areas as the structure will be precast before being transported to the respective construction sites. Hence, public safety will also be enhanced due to no on-site works.

The LRT3 project deploys 2,061 U-Trough girders linewide. As of 28 May 2021, 1,324 units (64.24%) of U-Trough girders have been casted while 929 units (45.08%) have been delivered.
