|Route outline (key)|
The B6057 follows the original line of the A61 in north Derbyshire, gaining its number when that road was moved onto its present bypass in the mid-1970s.
The northern end of the B6057, however, does not follow the ex-A61. It starts at a roundabout on the A6102 in the Sheffield suburb of Norton and heads south along Jordanthorpe Parkway to bypass the suburb of Jordanthorpe. This road actually opened as part of the B6158 and it is that road we meet at the next roundabout, after which we continue west to reach the A61 for the first time. The two roads cannon off each other at a roundabout and we now head south along the old A61 into Dronfield.
As the road starts to get built-up the B6056 comes in from the right at traffic lights after which our road is the dominant number in a short multiplex. The B6056 soon turns left at a triangular junction and we continue along Sheffield Road into the town centre. We pass the station before meeting the other end of the B6158 at a mini-roundabout. The road then goes under the Midland Main Line and leaves town along Chesterfield Road. There's a brief rural section before we go under the line again and go through Unstone.
After going over the railway we go through Unstone Green and then follow a straight road to a diamond GSJ on the A61. The unclassified road ahead leads into an industrial estate; in fact the mainline of the B6057 turned left just before the GSJ. It goes under the railway again to reach the Chesterfield suburb of Old Whittington. There's then another railway overbridge (at such a sharp angle the bracing makes it looks as though the road goes under two bridges rather than just the one. We now pass through light industry as we squeeze between the railway line and A61 before reaching a T-junction on the B6052.
There's a short multiplex to the right along that road to a large roundabout where we cross the A61 and B6050. In fact the multiplex is useless as it is our road rather than the B6052 which reappears on the far side. We then rejoin the ex-A61 (which was severed by the junction) and continue south into the town centre. After passing a campus of the University of Derby the B6051 turns right at a mini-roundabout and then reaches a gyratory where the B6543 leaves.
The remainder of the road is variably mapped as either the B6057 or B6543. We follow Holywell Street, then bear right by the museum to pass the Church of St Mary and All Saints: the one with the famous crooked spire. The road then descends to journey's end at a roundabout where every exit has a different number. Right is the A619 and ahead the A617. The road to the left is signposted as the A61 as it leads to a north-facing GSJ with that road but traffic can also continue ahead onto the A632.
