The Cathkin Roundabout lies at the eastern end of the Cathkin Bypass, a road which was built in the 1950s but only completed as a proper bypass through route in the 2010s. It is now, therefore, the southern part of the A730, which terminates on the A749 at the roundabout. The roundabout was built in c1973 when the southern part of the A749 was dualled. This dualling is somewhat unusual, however, as the two carriageways are widely separated as if they had been built to allow for future grade separation. However, it seems that the main reason behind this wide spacing is that the northbound carriageway is the original line of the road, and the southbound carriageway was built further east to avoid the need to demolish roadside properties. The northern arm of the A749 was dualled later in a more conventional manner, and a fourth arm heading east has also been added serving a housing estate

The three A road arms all have two approach lanes, and the A749 also has two departure lanes, as it is a dual carriageway in either direction. The central island is more or less a regular oval, despite the irregular arrangement of the four arms.
