The B3099 is a short B-road west of Westbury.
It in the Leigh Park area of Westbury to the south west of the town centre. From here it heads west and proceeds through the village of Dilton Marsh.
After leaving the village it goes along a road called Clivey before moving into Somerset and then turning sharply left just before reaching the railway line. The road ends at a 'give way' junction south of Standerwick on the A36.
Although the B3099 is described in the 1922 Road Lists as Westbury Leigh - Beckington it has always ended here and never actually reached Beckington.
