The A591 is a major road in the English county of Cumbria, which lies almost entirely within the Lake District national park. The road starts at a roundabout with the A590 close to Sizergh Castle and runs generally north west, bypassing the towns of Kendal and Keswick, ending on the A595 near Bothel. A 2009 poll by satellite navigation firm Garmin named the stretch of the road between Windermere and Keswick as the most popular road in Britain. The A591 was badly damaged during Storm Desmond in 2015, with part of the road washed away at Dunmail Raise, and had to be closed for five months. While it was closed a new trail for walkers, cyclists, and horseriders was built to the west of the road.Photograph: Diliff.
