Top 15 Humanity's Costliest Builds Unveiled

13. Extension of Dubai World Central Airport

Location: UAE's Dubai Entire Expense: $32 billion* Year Completed: 2030 The first freight flight took off from the single runway of the government-owned Al Maktoum Airport (Dubai World Central Airport) in June 2010, but the first passenger flight did not land there until nearly a year later. More than 100,000 passengers used the airport annually as of the first quarter of 2014. Over the next two years, that amount more than quadrupled, but it is still far short of what is intended once the airport is fully operational.

Expansion of Dubai World Central Airport, @archdaily/PPinterest Its yearly capacity is anticipated to approach twelve million metric tons of freight and about two hundred million passengers, who will be able to take advantage of the numerous stores and hotels located inside the complex. The airport's completion was put back ten years, from 2017 to 2027, due to the global financial crisis of 2007–2012; however, it is not anticipated to be postponed until 2030.

14. LRT at Eglinton Crossroads

Location: Canada's Toronto * Total Outlay: $10 Trillion Year Completed: 2021 On the first day of his administration in 2010, the late Toronto Mayor Rob Ford declared the abandonment of his predecessor, Mayor David Miller's, plan to construct a light rail system that would have run partially underground through midtown Toronto. The previous layout called for 43 stops to be dispersed over the entire city. It ends at Kennedy Station to the east and begins at Pearson International Airport to the west. Mayor Ford's new proposal served as a fantastic model for the twenty-five stations that would eventually make up Line 5, or the 19-kilometer Eglinton Crossroad. Crosslinx Transit Solutions, a group of over twenty-six organizations, was given the thirty-year contract to construct and manage the Eglinton Crossroad Line.

Only 6.2 of the 29 miles of track had been constructed by 2018, but Crosslinx was confident they would finish the project by 2021. Midtown Torontonians were greatly disappointed to learn in February 2020 that there would be another delay, with Metrolinx estimating a completion date of "well into 2022." Owing to the construction's seemingly never-ending delays, the Ontario provincial government committed $3 million CAD in March 2020 to assist nearby companies impacted by the ongoing work. Although there is still hope that "Line 5" will conclude in 2022, there are no assurances because of the COVID-19 epidemic.
