The route starts in South Elmsall at a junction with the B6422 close to the town's railway station, which lies on the Leeds to Doncaster line. We follow the High Street over the railway line, climbing before we TOTSO left into Mill Lane. We continueto the Minsthorpe Lane Roundabout on the A638 North Elmsall bypass. That road takes over for about 250 m to the next roundabout before the B6474 continues northwards through the village of Upton, where we zigzag right then left across an unclassified road.
The next 5 km take the route through open and almost flat countryside, passing Badsworth, traversing Thorpe Audlin, and crossing the A639 before reaching Wentbridge where, at a T-junction in the centre of the village, we meet the 'old', pre-bypass line of the Great North Road.
Since 1961 the B6474 has been extended to include this former stretch of the A1, providing links to the modern road at each end of the Wentbridge bypass. While both extensions end in LILO junctions linked to the northbound carriageway only, that running south of the village also gives access (via Wentedge Road, which bridges the bypass) to a LILO on the other, eastern side of the A1 – so that there is effectively a full grade-separated junction between the B6474 and the A1 here.
