|Route outline (key)|
The C4B serves the village of Fetterangus. It starts on the A952 at Denhead and heads southwest to the east end of the village. Here, at a T junction, all three arms are the C4B, which has a spur heading south east, zig-zagging through the fields, back to the A952 at Hardyards. The mainline, runs down the village street, and then turns south to Dunshillock. It is not entirely clear whether the C4B ends at the crossroads with the C5B, or continues the very short distance on to the A950.
