The A1111 winds across the Fens from the East Lindsey town of Alford to the seaside village of Sutton-on-Sea.
The road starts on the northern edge of Alford, turning east off the A1104. The road soon reaches Bilsby, where the B1449 turns right opposite a disused windmill to keep the easterly alignment of the A1111. We bear left and head northeastwards across open country. Although the terrain is flat this doesn't mean the road is straight - in fact it's rather winding.
The road bends sharply to the right in Markby then left again in Hannah before gradually turning from a northerly to northeasterly course. There are a few straight sections of road now, still with the usual bends, before the seaside resort of Sutton-on-Sea is reached. The A1111 runs into town along Alford Road to end at a roundabout on the A52 at the west end of the High Street. The coast is straight ahead.
Originally unclassified, the Alford to Sutton road was quickly classified, as the B1197. It was not until the late 1950s that it was upgraded to Class I status and became the A1111.
