The B2142 runs along Drakefell Road in the London Borough of Lewisham. The road was unclassified for many years but got its number by at least the 1980s.
Starting on the A2214 Lausanne Road north of Nunhead station the B2142 heads east along the residential Gellatly Road, which climbs to become Drakefell Road. After reaching a summit by Telegraph Hill Park the road descends once more and crosses a mini-roundabout before levelling out. We soon reach a sharp right-hand bend, after which we bear left to go over the Brighton Main Line and end just afterwards at double mini-roundabouts on the B218.
