Inside Saudi Arabia’s ‘THE LINE’: 16,000 Deep Piles Laid, 2.4 km Built In A 170-km Mega City Plan

Saudi Arabia has commenced large-scale construction activities on THE LINE, a planned linear urban development that forms the central component of the NEOM project in the country’s northwest. The project is a flagship initiative under the Kingdom’s Vision 2030 programme, which aims to diversify the economy and reduce long-term reliance on oil revenues through infrastructure, technology, and urban development investments. 

THE LINE is designed as a continuous structure extending approximately 170 kilometres, with a planned width of 200 metres and a height of 500 metres, stretching from the Hejaz Mountains to the Gulf of Aqaba. Satellite imagery and construction data indicate that extensive groundwork has been completed along the planned route, including the excavation of a wide trench and the preparation of foundations across multiple terrain types, such as rocky mountains, desert sands, and coastal plains. 

Phase One of THE LINE spans roughly 2.4 kilometres, accounting for less than 1.5 percent of the project’s planned total length. Despite its limited scale relative to the overall concept, this phase includes the construction of several major infrastructure assets intended to anchor future development. These include a marina capable of accommodating large vessels, a stadium with a planned seating capacity of 46,000, and associated structural and transport components. The development is organised into modular sections of approximately 800 metres each, allowing phased construction and independent completion of individual segments. 

THE LINE is intended to serve as the central urban component of the wider NEOM region, which includes multiple industrial, tourism, and technology zones. Timelines for subsequent construction phases and full project completion remain linked to infrastructure readiness, resource availability, and progress toward Vision 2030 milestones. Further updates are expected as the project transitions from foundation works to vertical construction and systems installation.
