The B193 is a short B-road in north London, presumably dating to around 1935.
The road starts on the A1000 Pricklers Hill and heads northeast along the residential Lyonsdown Road. After passing a small open space the road bears round to the right onto Longmore Avenue (Lyonsdown Road continues ahead) and descends steeply before going under the East Coast Main Line. Now much flatter, the road continues to a mini-roundabout where it continues ahead onto East Barnet Road, part of East Barnet's shopping area. At the next mini-roundabout by the war memorial the road bears left and climbs Cat Hill to traffic lights, where it ends on the A110.
