Opened in 2005, Chapelhill Roundabout is one of three new junctions constructed as part of the Three Towns Bypass. This saw the A78 moved out of the towns of Ardrossan, Saltcoats and Stevenston onto a new route curving around the urban fringe. Either side of the junction, the A78 is dualled, indeed the remainder of the route from here to its terminus on the A77 near Prestwick is all dual carriageway, punctuated at regular intervals with roundabouts.
The roundabout is situated where the bypass crosses the B714 from Dalry. It is therefore a simple 4-arm junction, with the A78 running roughly east-west and the B road north-south. The B714 has been slightly realigned at the junction, moved a little to the east which has removed an old kink in the route. It then continues south into Saltcoats, where it crosses the former A78, now the A738.
