The B8075 is a direct north-to-south link between the A84 and the A811 across the wide floodplain of the River Forth.
The road starts at a T junction with the A84 a little to the east of the better remembered fork for the A873. The northern half of the road is almost dead-straight, before a slight kink and another long straight. Both sections of the road run through open fields with just a scattering of houses along the road, no more than a dozen on the whole 2-mile route. Then, just before reaching the A811, the road curves round to head SSW and cross the River Forth at Gargunnock Bridge. Soon after, the terminus is reached at a simple T-junction with the A811.
The B8075 was not originally classified in 1922. However, despite its high number for a Zone 8 B-road, it was classified a decade later in 1932. The route has remained unchanged except for the removal of the railway line and level crossing at the southern end, just yards from the A811.
