The Trans-Siberian Railroad connects Moscow and Eastern Russia with Japan, China and Mongolia. 

06) Burj Khalifa, Dubai, UAE

The Burj Khalifa in Dubai is the tallest building in the world and tallest man made structure on land ever’ which stands at a record breaking 828m tall more than 160 stories. It rises above the Dubai skyline and holds many world records. Completion date: January 4, 2010

07) Akashi Kaikyo Bridge, Japan

It's took 2 million workers, 10 years to construct the Akashi Kaikyo Bridge. It connects the city of Kobe, on Japan's mainland, with Iwaya on Awaji Island. It's the longest suspension bridge in the world, with a length of 1,991m. Completion date: April 5, 1998.

08) White Pass and Yukon Route Railroad, Canada

Built during the Klondike Gold Rush and financed largely by British investors, the "railroad built on gold" was constructed in just 26 months, using 450 tons of explosives to blast through Canada's coastal mountains. The railway still uses vintage cars, the oldest dating back to 1881.Completion date: July 29, 1900.

09) Tokyo Sky Tree, Tokyo

The Sky Tree's reinforced concrete center column is separate from the surrounding steel framing and incorporates an earthquake-resistant design similar to that used in pagoda temples. Completion date: May 22, 2012.

10) International Space Station

The International Space Station cost $100 billion to build and involved 100,000 people in 15 nations. It also ranks as one of the more unusual construction sites, located 354 kilometers (220 miles) above Earth. Completion date: Ongoing.
