The contractor tunnelling beneath thousands of inner Sydney homes to make way for the WestConnex motorway has ruled out using explosives to blast through hard rock on the final stretch of the $16.8 billion mega-tollroad.
Joint venture contractor Acciona Samsung Bouygues previously sought planning permission to allow the use of controlled blasting to break rock for excavation on sections of the underground M4-M5 Link from Haberfield to St Peters.
Construction is underway on the Rozelle Interchange, which will connect the new M4-M5 Link tunnels with Anzac Bridge and Iron Cove Bridge.
