With joining in action, we’re doubling down (pun intended!) on progress at CR111.

Looking forward to keeping up the momentum and delivering safe, high-quality tunnels for the future CRL!

Our second autonomous tunnel boring machine (TBM), Hera, has been launched at Defu Station and Tunnels, MRT Cross Island Line (CRL) Phase 1.

This follows the launch of TBM Daphne in March this year—a first in Singapore. Since then, Daphne has made good progress underground—completing 537 out of 984 concrete rings, forming 760 m of the finished tunnel lining. Both Daphne and Hera, named after Greek goddesses, are boring twin tunnels—each about 1.4 km long.

With Hera now in the ground, we’re moving steadily ahead with the twin tunnels. Both machines are equipped with autonomous features to make tunnelling safer, faster, and more precise.

Stay tuned for more updates!
