The B5086 is a short link road in northern Cheshire.
Starting from a mini-roundabout on the B5085 at Row-of-Trees in Davenport Green, it heads northeastwards along Knutsford Road through the suburbs to reach a roundabout at Fulshaw Cross.
Originally the B5086 ended here on what was the A34. However, when that road was rerouted onto the Wilmslow bypass the B5086 was extended north along the pre-bypass road to reach the centre of Wilmslow. Here the route ends at a set of traffic lights on the A538, which has taken over the next section of the pre-bypass A34.
The former A34 between Fulshaw Cross and the bypass at Harden Park is also signed as a branch of the B5086.
