Montfode Roundabout

Montfode Roundabout was built in 2004 as the northern end of the Three Towns Bypass around Ardrossan, Stevenston and Saltcoats in Ayrshire. It is where the A78 turns inland away from its historic route, which has been renumbered as the A738. The ruins of Montfode castle are in a field a short distance to the north east, and its predecessor lies in a housing estate to the south east of the junction.

The roundabout is a simple 3-arm junction, which was built offline to the east to provide roughly equal angles between exits. This means that both the northern arm of the A78 and the A738 are turned to meet the junction. The third arm is the A78 bypass which heads west around the three towns, and thanks to further bypasses it doesn't rejoin its historic route until it is south of Irvine, over 10 miles away.
