|Route outline (key)|
The A159 is a rather short primary route in northwest Lincolnshire which appears to have altered little over the years, although both ends are now in slightly different places.
The road begins at a signalised crossroads on the south side of Gainsborough where it meets the A631 and A156. It heads north along the pre-bypass A631 through the town, until the B1433 turn to the right marks where that road used to head off to the right and the A159 used to start.
After leaving town, a 14' 6" high bridge under the little-used Gainsborough to Brigg railway line and some fast, straight sections take us into Blyton, which has sharp bends at both ends of its main street. There are then some more straight sections interspersed with the occasional bend which lead to the prettier (and larger) village of Scotter. On the northern edge of the village, North Moor Road turns off to the left; this is straighter and less built-up than our route which it parallels - but for some reason is unclassified.
Messingham is the next village, before we pass over the M180. Getting to this motorway is difficult, as you have to go into Scunthorpe to come right back out again. However, the whole of the A159 appears lightly travelled, so presumably traffic volumes don't require a junction here.
The A159 carries on into Scunthorpe down another straight, wide section of road, where it is easy to exceed the 30mph speed limit, especially given the fast rural sections that have previously been traversed. There is a TOTSO right at a set of traffic lights, followed immediately by another TOTSO left at a second set. This is to cross the B1450, the original line of the A18. The end of the A159 is reached about half a mile further on at a roundabout on the current route of the A18. The A159 used to continue further on into the town centre, perhaps another half-mile or so, but this is now unclassified.
