A turning circle (known as a "cul-de-sac" in the United States) is a widened area of road that allows vehicles to turn more easily. Often, but not always, a turning circle is circular in shape and located at the end of a dead-end street ("cul-de-sac street", "blind alley", "close", "no through road"), resembling a frying pan. Either there is no central island or the island is traversable (for example, not taken up by parking spaces or greenery).

Where to find them

A turning circle may occur along a road instead of at the end. This can happen when more houses are built later and the road is extended. The nodes of 58489782 (Visualise) on way Arthur Road, Wokingham are examples of this. Typically houses leading up to and on the turning circle are noticeably older than the houses beyond it.

In the United States, turning circles are very common in suburban planned residential areas to increase. In some areas, every street ends in a turning circle, and a turning circle may appear at every bend in a road.

How to map

Place a node that is part of the road at the center of the widened area and add the tag:

History

As with most tags in OpenStreetMap, this tag is based on the British English term "turning circle", and refers to turning places regardless of shape, including circular, square, triangular and otherwise.
