World’s Largest Bridge To Stretch 40km Long

Construction on what would become the world’s longest marine causeway, connecting Qatar and Bahrain, is due to begin next year, and what a project it is: We’re talking about a bridge more than 40km long, costing around $US3 billion.

Somewhat adorably named the Qatar-Bahrain Friendship Causeway, this massive bridge is expected to take around 4.5 years to complete and cost somewhere between $US2.3 and $US3 billion, but should be a great help for travel between Qatar and Bahrain. The trip currently takes more than four hours and will be reduced to 30 minutes on the bridge, and those in charge expect 10,000 to 20,000 vehicles per day to use it.

For a sense of scale, here’s a chart that compares the bridge to other very large things. Of course, I need a scale chart to tell how big a blue whale is, which sort of defeats the purpose of measuring this bridge in blue whales, but still: This is one large bridge.

Three Giant Wind Turbines Turned On at Once at Bahrain World Trade Center

What you’re looking at isn’t a render or merely a concept of some fanciful building that’ll never actually become a reality. No, what you’re looking at is an actually photograph of the new Bahrain World Trade Centre, a pair of pointy skyscrapers with three propellers with 95 foot diameters between them. And this week, they activated all three turbines at the same time. Now that they’re all running, they’ll be providing 10-15% of the energy for both towers, which will save loads of money over the years.
