PUTRAJAYA ROUNDABOUT - WORLD'S LARGEST ROUNDABOUT

Persiaran Sultan Salahuddin Abdul Aziz Shah or Putrajaya Roundabout is the main thoroughfare or roundabout in Putrajaya, Malaysia. It is world's largest roundabout with a diameter of 2.2 miles. It was named after Almarhum Sultan Salahuddin Abdul Aziz Shah of Selangor, the eleventh Yang di-Pertuan Agong.

NOTE:
The government of Trinidad and Tobago has disputed the Putrajaya Roundabout's title, using its Facebook page to boost the claim of Queen's Park Savannah. This park, in the center of the Trinidadian capital of Port-of-Spain, is also surrounded by a perimeter road, which was made one-way in the late 1970s to alleviate rush hour traffic. The park's 2.3-mile circumference is indeed a little longer than the Putrajaya Roundabout, but there's one problem: The Caribbean "traffic circle" isn't anything like a circle. In fact, to do a full loop, you'd have to turn no fewer than five 90-degree corners.
