The B7037 is a rural road in east Ayrshire. It was originally unclassified but had gained its number by 1932.
The road starts on the A71 Galston northern bypass and heads into town along Titchfield Street, the original line of that road. After bearing right a T-junction is reached where we turn left and multiplex along the A719 over the Burn Anne to traffic lights. Here the A719 turns left whilst the B7037 regains its number by turning right; this is our road's original northern end.
We head south along Wallace Street towards Barr Castle but TOTSO left into Station Road before reaching it. There is no sign of the old station. The road then climbs out of town, zigzagging right then left to skirt the grounds of Cessnock Castle. We then avoid the summit of Sornhill before heading southeastwards across undulating terrain. Presently the road bears round to the right and heads south through a wood before ending at a T-junction on the B743 opposite an entrance to Sorn Castle.
