The Leeds Outer Ring Road is a main road that runs around most of the perimeter of the city of Leeds, West Yorkshire, England. The ring road is approximately 25 miles (40 km) long and consists of single and dual carriageways. Hence the road is not a loop and so is not a true ring road, although it is designated as such. For the rest of the way between Farsley and Colton the road is the A6120 and it is a mixture of single and dual carriageway as far as Austhorpe. The ring road becomes the A63 road following a short concurrency and ends in Colton.
