Two of 24 concrete spans erected for the "Skytrain" section of the new rail line to Sydney's north-west suburbs may need to be pulled down after cracking.
The skytrain spans, which have an average length of almost 40 metres across the project, are made up of pre-cast concrete segments locked together with steel cords.
But Transport for NSW, which confirmed the cracking after enquiries from Fairfax Media, says there should be no delay in the overall construction of the $8.3 billion Sydney Metro NorthWest project, due to open in early 2019.

On Thursday, Premier Mike Baird and Transport Minister Andrew Constance announced the early and under budget completion of tunnelling for the rail line – a mammoth undertaking that has involved drilling 15-kilometre twin tunnels.
But to the west of the tunnelled section, progress has been patchier on the eight kilometres of elevated track that will form the Skytrain and viaduct parts of the rail line.
These sections, running from Bella Vista to Cudgegong Road past Rouse Hill, are being built by Italian consortium Salini Impregilo.

Fairfax Media revealed last year the consortium had already claimed a $50 million contract variation, following design disputes and the discovery of asbestos at a construction site.
The latest issue involves cracking in the pre-cast concrete used to form the elevated rail track. The Skytrain is being built using two gantry cranes to assemble about 1200 pre-cast segments up to the level of 130 concrete piers.
These segments then form "spans" between the piers, and are partly held in place by steel cords that run through the segments. Across the whole of the project, these spans have an average length of about 40 metres.
