|Route outline (key)|
The B193 is a short link road in the far west of County Londonderry.
The route starts at Nixon's Corner, two and a half miles south-west of Derry city centre, at the point where the A40 Derry to Carrigans road TOTSOs left. Heading west across rolling fields, the dead-straight B193 quickly reaches Killea and the border with County Donegal, marked by a bridge over a stream. The road ahead is the R237.
Nixon's Corner to the border was originally the western end of the now defunct B71 but gained its present number following reclassification of the Derry – Nixon's Corner – Carrigans route as the A40 in the mid-1920s.
