North-South Corridor enters toughest phase as hard rock and tight tunnels slow work
Singapore's North-South Corridor has entered its most technically demanding construction phase, with hard rock, groundwater and tight spaces slowing progress. At Novena, tunnelling passes within about 1m of the North-South Line, requiring smaller excavation sections and extra ground support. The 20km project includes an 8.8km viaduct and 12.3km tunnel, with the viaduct expected to open from 2027.

LTA: North-South Corridor works hit hard rock and water seepage at Novena, Thomson
Singapore's Land Transport Authority said tunnelling for the North-South Corridor has run into unexpected ground conditions at Novena and Thomson, including hard rock and underground water seepage. At Novena crews are digging the northbound tunnel section by section just 1m below the operating North-South MRT line, while in Thomson harder rock was found about 10m closer to the surface than expected. LTA said it is monitoring progress and will update the completion timeline later; the corridor was previously slated to open in phases from 2027.
