This Roman Road was part of the Alternative route from Lincoln to York used when the Humber was impassable, and is thus associated with Ermine Street in the Antonine Itinerary.

The A1500 starts in the village of Marton, at SK840820, and runs south of east along the Roman alignment.

The junction in the Village is actually a crossroads: The Roman alignment is maintained toward the west, crosses the River Trent to Littleborough, Nottinghamshire, and can be intermittently discovered nearly to Bawtry.

The name Horncastle Lane continues on the other side of the A15, but that is a minor road not part of the A1500 designation.

The Roman Road alignment from SK947784 near Scampton is maintained across fields, and also makes a junction with the A15 Ermine Street at SK973774.
