The Line is a proposed smart linear city in Saudi Arabia in Neom, Tabuk, currently under construction, which is designed to have no cars, streets or carbon emissions.
The 170-kilometre long city is part of Saudi Vision 2030 project, which Saudi Arabia claims will create 380,000 jobs and add $48 billion to the country's GDP.
The Line will be the first development in Neom, a planned $500 billion city.
The city's plans anticipate a population of 9 million.
