The booming Gulf city state of Dubai will add another feather in its cap with the construction of world's longest hotel strip at a cost of $27 billion, developers said Monday.

"Bawadi" will feature 31 hotels, many theme-based, offering more than 29,000 rooms projected to host 3.3 million guests by 2016, said Saeed al-Muntafiq, chief executive of Tatweer, which will develop and manage the project.

The development will be built on a 10-kilometer (six-mile) strip of land with total investment estimated at 100 billion dirhams ($27.2 billion), Muntafiq told reporters and tourism industry executives.
