NEOM has asked firms to submit revised offers by 10 November for the contract to build the tunnels that will serve as the railway junction connecting the Spine with the NEOM Connector. The previous deadline was 27 October. Known as the Delta Junction, the project involves 26.5 kilometres (km) of tunnelling work that will be split into two lots, one for the north and the other for the south.

NEOM invited selected contractors to submit bids to complete the tunnels in April last year. The evaluation process neared completion earlier this year, but stalled for unknown reasons. The work was previously divided into five packages. Each package involved excavating about 5km of tunnels through hard rock using drill-and-blast and cut-and-cover techniques.

The Spine is the infrastructure corridor running alongside THE LINE. It includes a high-speed rail line that links to the Connector South, which runs to the OXAGON industrial zone and the port at Duba on the Red Sea coast.
