Construction of Singapore’s Mass Rapid Transit (MRT) expansion progressed with the successful tunneling directly beneath the Keppel Viaduct, a major roadway carrying live traffic. Engineers completed the challenging task by cutting and drilling through seven piles supporting the viaduct. This method minimized disruption to traffic flow during the tunnel boring process. The project represents a significant engineering feat, demonstrating the ability to build new infrastructure within a densely populated urban environment. This stage of construction is part of the larger CCL (Circle Line) Stage 6 expansion project. The completion of this section allows for continued progress on the overall MRT network expansion, enhancing public transportation options in Singapore. Further details regarding timelines and potential future disruptions were not immediately available.
