10. The Incheon Bridge
Location: Incheon, South Korea
Total Expense: $1.3 Billion*
Completed Year: 2009
The Incheon Bridge in South Korea, developed and constructed primarily by the Samsung C&T Corporation joint venture, was completed in 2009. With a total cost of $1.3 billion, this project was certainly not inexpensive. However, witnessing this engineering marvel up close reveals the reasons behind its significant investment.
The Incheon Bridge resembles a real-world Hot Wheels circuit that children often envision turning into swimming pools. This impressive structure connects Incheon International Airport to Songdo, the city’s primary business center. Spanning 13.2 miles across the Yellow Sea, it significantly reduces travel time, saving passengers nearly an hour on each journey compared to alternative routes.
