|Route outline (key)|
The B6422 in south-west Yorkshire connects Scawthorpe in the Doncaster Metropolitan Borough area to Hemsworth in the Wakefield Metropolitan Borough. The road was originally unclassified but had gained its number by 1932.
The road starts on the A638 (former A1) in the Doncaster suburb of Scawthorpe. B6422 traffic may only turn left but all other movements are allowed. We head west and enter open country almost immediately but then bear right to run through a small, apparently unnamed settlement. After passing reclaimed industrial land we go under the A1(M) then skirt the edge of Pickburn to enter Brodsworth. The road then winds along - and out of - a small valley to reach a T-junction on the southern edge of Hooton Pagnell. It TOTSOs right and passes a high wall on the right, with the hall grounds beyond.
After passing the hall and the church we enter the residential part of the village and squeeze into the main street, the road widening again as it continues northwards. On the northern edge of the village we bear left then descend to cross a stream and reach South Elmsall. The B6474 bears right in the town centre then we follow the main shopping street, merging seamlessly into Moorthorpe. Here we pass a cemetery then go over the Sheffield to Wakefield railway line above Moorthorpe station. On the far side of the line we reach South Kirkby.
On the far side of the town we bear right to reenter open fields. After passing an industrial estate we cross a roundabout on the A628 Hemsworth bypass before running into town along Kirkby Road. After passing shops and the market the B6273 comes in from the left and TOTSOs, taking on the road ahead. Our road ends here.
