The B1415 is a short link road on the southern edge of the North York Moors. The road was originally part of the mainline of the A170 but got its number when that road was diverted onto its present route in the early 1930s.
The road starts on the A170 on the northern edge of Allerston and heads south along Main Street through the village. On the far side, just after the NSL sign, the road TOTSOs left onto a winding S1 road. Some maps now claim the B1415 to be unclassified (although North Yorkshire CC disagree); this is presumably the reason.
Presently the road approaches Ebberston, another linear village following a road heading south of the A170. This road is met on the southern edge of the village and the B1415 TOTSOs right to remain in open country. There's now a short run south to a triangular junction on the B1258, where the B1415 ends.
