The A6145 is a short non-primary A-road in western Bolton. It was originally numbered B6200 and appears to have gained its present number in the 1960s.
The road, better known by its name of Hulton Lane, runs a ruler-straight course north-south between the A579 and A676. It was earlier typical of many radial routes in Bolton in being a wide S2 road, although somewhat unusual in that both terminal junctions were simple give-way T-junctions.
More recently both of these junctions have been signalised, and the layout of the road between them has been completely modified, the carriageway having been narrowed by the addition of cycle lanes, hatching, parking bays, and traffic islands along is length. Two mini roundabouts complete these traffic calming measures, although the roads that lead off them lead only to housing estates.
