|Route outline (key)|
The B787 is a largely urban B-road to the west of the Renfrewshire town of Johnstone.
It starts at traffic lights on the B789 in Johnstone town centre and heads south along Macdowall Street. The road is largely residential from the outset. It continues along Kilbarchan Road and descends to a mini-roundabout, from where a spur heads off to the right to cross the Black Cart Water to end on a dumbbell GSJ with the A737 Johnstone bypass.
The mainline of the B787 turns left at the mini-roundabout to cross the Ayrshire Coast Line by Milliken Park station and reaches a roundabout shortly afterwards. This was the original southern end of the B787 as it reached the A737. However, when that road was moved onto the bypass the B787 took over the old road to the south. It therefore turns right and continues along Beith Road.
The road soon reaches the edge of town and continues on across fields, although there is a school on this section meaning it is not completely rural. A few hundred yards later the road becomes residential again as it reaches Howwood. It meets the B776 before continuing west along Main Street. After leaving town the road bends to the right and ends at a T-junction back on the A737.
