|Route outline (key)|
The B6131 is a short urban B-road in south Yorkshire.
The road starts on the A637 by the church in Darton and heads east, quickly going over the River Dearne and under the Barnsley to Wakefield railway line by the station. The road continues east and moves imperceptibly into Staincross, where it crosses the B6428. The road ends on the far side of Staincross at traffic lights on the A61.
None of the above was actually classified in 1922 but it was numbered as a western extension of the B6131 within ten years. The original line of the B6131 started slightly further south on the A61 at New Lodge and headed east into the village of Carlton. The T-junction by the church was the original eastern end of the B6131, where it ended end-on with the B6132.
The original section of the B6131 was later renumbered as an extension of the B6132, which it remains.
