This article is about the current B730 in Ayrshire.
For the original B730, now part of the A702, see B730 (Thornhill - Dalry)

The B730 is a secondary road in Ayrshire. The road was originally unclassified but had gained its number by 1932.

The road starts in the hills on the A713 north of Patna and heads northeastwards signposted Drongan. The road goes over a hill and then descends to Littlemill where the road turns sharply left to cross the Water of Coyle, then continues north skirting the eastern edge of Drongan and following a freight-only railway line to Coalhall and the A70. There's a short multiplex to the east under the railway line (which is a 14' low bridge) before the B730 turns left signposted Tarbolton to regain its northerly course.

The road continues across the fields to Stair, where it crosses the River Ayr at a narrow weak bridge. The road climbs out of the valley and goes over a railway line before reaching the B743, which is crossed at a slightly staggered crossroads. Less than a mile further on Tarbolton is reached. The B744 comes in from the left on the near side of the village and is the junior partner in a short multiplex along Montgomerie Street. After the two roads separate it's not long before the A719 is reached in Fail. There's a short multiplex to the right and the B730 continues on.

After a couple of miles the A77 is reached at Bogend. Until the 2010s this was a simple crossroads but a bridge has now been built to avoid B730 traffic having to cross the busy dual-carriageway at grade; there's a roundabout at each end. Just round the corner the B730 TOTSOs left (ahead is the B751) and the road follows a dead-straight course for a few hundred yards before bearing left and crossing a few fields to enter Dundonald. We run along Main Street and Drybridge Road before meeting the A759 on the far side of town; this is crossed at a staggered crossroads.

The road follows a dead-straight route across largely flat land for over a mile before going over a narrow railway bridge, whose flow is controlled by traffic lights, to enter Drybridge. Here we meet the River Irvine which is followed for a few hundred yards until we cross it at a narrow bridge, where traffic heading north has to give way. On the far side we go under the A71 and then a short spur of the B730 turns right to meet that road at a roundabout. The mainline continues ahead along Dundonald Road into the centre of Dreghorn, where it ends at traffic lights on the B7081.

When first classified the B730 continued ahead down Station Brae across the Annick Water to run through Bourtreehill. The road's course is now a bus-only road and is still easy to follow as one of the few roads in the area which is not part of the new housing estates. After climbing Corserine Bank the road ended on Lochlibo Road, the pre-bypass route of the A736. This section of road lasted until at least the 1970s but was presumably downgraded when the houses surrounding were built.
