As The Conco Companies have been in involved in many of the largest, most distinguished projects in the Western United States, we are always interested to learn more about some of the megaprojects going on across the globe. Here is a quick look at a few of them.
Originally opened in 1914, the expansion of the Panama Canal is expected to be finished in 2016 at the cost $5.25 billion and 11 years to build. The project consists of a new 3.8-mile long channel for the new locks and is estimated to have required 4.4 million cubic meters of concrete. This new phase of the canal was necessary to widen and deepen the channel to better accommodate modern ships which have grown in size.
Another impressive project is the world’s largest dam in China that took 17 years and an estimated $30 billion to build. The Three Gorges Dam is built entirely of steel (510,000 tons) and concrete and is a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in Yiling District, Yichang, Hubei province, China. The dam measures 595 feet tall, 131 feet wide and over 7,600 feet long. There are 32 main turbines that produce the electricity.
One mega-project from right here at home is the recently completed east span of the San Francisco-Oakland Bay Bridge, which holds the Guinness World record for the widest bridge in the world. It is estimated to have a cost of 6.4 billion and is the most expensive public works project in the history of California. The east span of the bridge is 258.33 feet wide and consists of 10 general purpose lanes.
