The A15 has come down from the Humber Bridge and rises up and yet underneath the roundabout as it goes into the chalk hills of the Lincolnshire Wolds. These wolds have swept well under the river and alluvial soil and sweep up again. There is a chalk cutting south of this roundabout and still rising. In fact the road rises quite further as it rides on top of the wolds.

It is a dual carriageway from the Humber Bridge all the way to the M180. It is grade separated throughout, with a narrow strip and what is effectively a soft hard shoulder.

The old route of the A15 (now the B1206) crosses the present route at the next junction after the one to Barton. This is also a junction for heavy lorries to double back to New Holland, avoiding Barton. There is a road to the center of Barton too. It would have been a junction for the industrial area on the eastern side of Barton too (the road to New Holland so far) but it failed a public inquiry. The road appeared for a while on the A-Z road atlas and they then had to remove it.
