The World's Top 12 Expensive Bridge Ventures

2. Canada's Confederation Bridge

Situated on Canada's Prince Edward Island Founded in 1997 Price: *$990 million The Confederation Bridge, sometimes known as "The Fixed Link," connects Prince Edward Island to the mainland of New Brunswick. The construction of the Confederation Bridge lasted four years, starting in 1993 and finishing in 1997. To finish it, $990 million (or CA$1.3 billion) was needed. On May 31, 1997, the bridge had its official opening to the public.

The government was now permitted to impose a toll to pass the bridge, according to this proclamation. Over 5,000 workers—a mix of day laborers and specialized engineers and managers—were needed to complete the bridge. The new bridge may have contributed to the 740,000 increase in visitors to Prince Edward Island to 1.2 million. The annual Terry Fox Run, a marathon that registers 5,500 participants annually, takes place at the Bridge, according to Facebook. The Prince Edward Island capital of Charlottetown always benefits greatly from the Terry Fox Run in terms of tourism.

3. China's Sidu River Bridge

Found in: Yesanguan, China's Badong County, Hubei Founded in 2009 Price: $100 million The Sidu River Bridge, commonly referred to as "Siduhe," is an astounding 4,009 feet long. It is three thousand feet at its longest span. The terrifying pictures show that the clearance below is 1,627 feet. The Yangtze River and the Sidu River combine to produce the Three Gorges, where the Sidu River is crossed.

Not only is it one of the most costly bridges globally, but it also has the highest clearance, only surpassed by the 1,854-foot-tall Duge Bridge (completed in 2016). The constructors (CCCC Second Highway Consultants) had to utilize a rocket to deploy the first suspension cable. Conditions imposed by the bridge made it impossible for builders to use what they typically would—helicopters or boats. Nevertheless, the rockets were successful in saving money and time. In a single day, they completed the installation.
