It's a 12 lane Road - 6 lane (per direction) - traversing the various districts of Dubai. This "spine road" traverses Deira, Sharjah, Jumeirah, Al Barsha and other areas of Dubai to Abu Dhabi. You'd see some of the most prominent skyscrapers along this road. The metro rail is located just adjacent to it. We can say that Dubai was planned in a linear fashion, with districts defined by their prominence, and their land use. Some of the world's most expensive piece of real estate can also be found here.
