🚧 on Cross Island Line ( ) Phase 1 Works

🔧 Tunnel Boring Machines (TBMs) don’t just carve out MRT tunnels, they also install concrete linings simultaneously? These engineering workhorses are key to building Singapore’s underground rail network safely and efficiently.

Since November, tunnelling works for CR7 station along Defu Avenue 1 and Avenue 2 as well as the CR8 Hougang Interchange Station, have been completed! 🎉 Despite challenges like tunnelling beneath buildings and live North-East Line tunnels, our teams have maintained close operational control to keep the ground and surrounding structures stable as the TBMs passed through. 💪

Stay tuned for more updates as we move into the next stages of construction! 🚇
