Heathfield Junction is a signalised T-junction on the northern side of Irvine town centre. It is the northern start of the towns Northern Approach Road which was completed in 1974. At that time the A78 still passed through this junction, but a couple of years later the Irvine bypass opened, and the A737 was extended over the former A78 route through the town. The Northern Approach Road, named as Marress Road as it heads west from the junction, is a dual carriageway, part of the never completed road network for the New Town. It bypasses the old town centre, and facilitated the construction of the new shopping centre, which replaced the old town bridge. The other two routes are single carriageway, but all three approaches have two lanes to separate turning traffic.
