A turbine interchange connects the SR 9A and SR 202 in Jacksonville, Florida, USA. Also known as a whirlpool interchange, this structure consists of left-turning ramps sweeping around a center interchange, thereby creating a spiral pattern of right-hand traffic. This type of junction is rarely built, due to the vast amount land that is required to construct the sweeping roads.
