The B41 is a short B-road in south County Londonderry.
The road starts at a roundabout on the B40 in the centre of Draperstown. The road on the far side is the B47 which seems at first to be a logical continuation of our road suggesting they should have the same number. However, that road did not reach here until the mid-1920s explaining the numbering. Our road heads northeast out of town along Tobermore Road before continuing east across the fields. A couple of miles later the B41 reaches Tobermore.
In the centre of the village the B42 Lisnamuck Road comes in from the left. Theoretically the B41 should end here but according to the road signs it continues as the dominant number in a useless multiplex for another few yards before ending at a mini-roundabout on the A29.
