The B6252 is a short B-road in west Yorkshire.
The road starts at a mini-roundabout on the B6251 in the centre of Barnoldswick and heads northeast along Skipton Road, soon crossing the Leeds & Liverpool Canal. Shortly afterwards, Coates Lane turns off to the left. This was the original line of the B6252 until the present road was built in the 1950s; the old road is narrow and crosses the canal twice more.
Old and new roads join again in a cutting after crossing a few fields. The B6252 then continues east and quickly reaches Thornton in Craven. The church appears isolated but the rest of the village soon follows and the road ends at a T-junction on the A56.
