44-412: A population more in the region of 120,000. Until December 2004, the route of the A78 went through the "three towns" – namely Ardrossan , Saltcoats and Stevenston . The result was a highly congested section with numerous traffic lights making progress slow. To counter this a bypass was constructed with two additional entrance/exit points other than the ends in the form of roundabouts . The section at

This keeps slow traffic in the slowest lane even if drivers neglect to change lanes, while allowing drivers who wish to pass the choice of changing lanes to do so. Some climbing lanes extend slightly over the crest of the hill, to allow slow vehicles to regain speed. As trucks and recreational vehicles must use low gear to descend slowly, an additional lane may also be built on
77-820: The Ardrossan end is a single carriageway road with a climbing lane . The other two sections are dual carriageway with two lanes in each direction. The existence of the bypass meant that the section through the towns previously labelled A78 became a continuation of the A738 which previously formed a concurrency with the A78 through Stevenston before diverging to form Boglemart Street and subsequently many other streets in Saltcoats and Ardrossan. Many sources available today still don't acknowledge these changes, for example Google Maps. The new road can easily take 10 minutes off any journey which would otherwise involve travelling through

Much of the road is single carriageway – both for a short distance through Greenock and a 21-mile stretch between Inverkip and Ardrossan. The rest is dual carriageway – between the Eglinton and Warrix interchanges there are in fact 3 lanes in each direction, and
110-413: The road is constructed to motorway standard (with full grade separation at junctions) save for a lack of hard shoulders. The road very rarely appears busy on this stretch – the adjacent New Town development area of Irvine, North Ayrshire (which includes Kilwinning , Dreghorn and Girdle Toll ) had a population of just over 50,000 in the 2001 census; the town planners designed the infrastructure for
