Dubai is building another seemingly impossible project by Laura Lorenzetti @FortuneMagazine August 5, 2015, 4:26 PM EDT E-mail Tweet Facebook Linkedin Share icons Looking for a new skiing destination? You might want to add the desert kingdom of Dubai to your list. The Gulf emirate has announced plans to build the world’s longest indoor ski slope, which will be part of a larger construction project that when completed will be home to the world’s tallest residential building and the largest dancing fountain, reported The National. The first phase of the new complex, called Meydan One, will cover 40 million square feet and cost $6.8 billion to build. It’s set to be completed by 2020. This isn’t Dubai’s first indoor ski slope, but the new slope will be three times longer than Ski Dubai in the Mall of the Emirates, which already holds the world record for being the world’s largest indoor ski resort. The new ski run will be 1.2 kilometers — or 0.75 miles — long. Dubai is well-known for its elaborate construction projects. It is already home to the Burj Khalifa, the world’s tallest tower at 2,722 feet high.
