A683

A683 is a designation that can refer to several different things, most notably a highway and a large iceberg.

In the United Kingdom, A683 is a numbered road in Lancashire. It runs from the A687 near Caton to the A585 in Blackpool. The road connects several towns and villages, including Lancaster and Fleetwood. It is a significant arterial route within its region.

Separately, A683 was the designation given to a colossal iceberg that calved from the Larsen C ice shelf in Antarctica in July 2017. At the time of its detachment, A683 was one of the largest icebergs ever recorded, covering an area of approximately 5,800 square kilometers. Its immense size made it a subject of considerable scientific interest and monitoring as it drifted through the Southern Ocean. The iceberg's journey was tracked by satellite imagery and various research institutions, with particular attention paid to its potential impact on shipping lanes and marine ecosystems. A683 eventually broke up into smaller pieces.
