The B739 is a link road near Prestwick Airport.
It starts on the A719 at Raith, a mile or so east of the A77 Ayr bypass. The road heads northwest across the fields before turning sharply left to descend to the A77, which it goes under without a junction. On the far side the road runs through Prestwick Airport, with high fences on both sides of the road before a glimpse of fields takes us into Monkton.
Originally the B739 bore left into Tarbolton Road to end on the A77 Main Street. Now, however, it continues along Baird Road to meet Kilmarnock Road (also the former A77). Here, through traffic is directed right to reach the bypass but the B739 TOTSOs left to follow a traffic-calmed road into the centre of Monkton. It goes straight across a slightly staggered signalised crossroads and continues along Station Road; the traffic-calming continues.
On the edge of town we meet the airport again, although this time it's only on the left. The road follows the boundary fence, with an industrial estate on the right accessed by roundabouts, and we soon end at a further roundabout on the A79.
The whole of the B739 was unclassified when road numbers were first allocated in 1922. However, in the 1950s the growth of Prestwick Airport destroyed the old road east of Prestwick (the B742, which still exists to the south of the A719). A new Class II road was allocated to the north of the airport and given the B739 number.
Originally the B739 started on the A719, as it does today, and headed west into the centre of Monkton, where it ended on the original line of the A77. In more recent years that road was also severed by further expansion of Prestwick Airport. The B739 was extended along a new-build road to end on the A79, which skirts the airport to the west.
