A684 road

East of the M6, the road descends the "Black Horse" hill and passes through Sedbergh where there is a short diversion to avoid the main street and a difficult right-angled bend.

Because of this, heavy eastbound traffic must leave just before the bridge and proceed onto an unclassified road through Hardraw and then turn south onto Burnt Acres Lane bringing the vehicles back to the A684 just east of Hawes town centre.

After passing Askrigg and bridging the confluence of the Bishopdale and Walden Becks, the road meets the B6160 from Addingham where there is a grade II listed AA phone box.

[3] It then passes through West Witton, Wensley, Leyburn (where it runs in tandem with the A6108 for a short distance), Constable Burton, Patrick Brompton and Crakehall before arriving at Bedale.

On 16 July 2014 the Department of Transport announced the go-ahead for the villages of Leeming Bar and Aiskew and the town of Bedale in North Yorkshire to be bypassed.
