This article is about the Class III road numbered C401 maintained by DfI Roads.
For other roads numbered C401, see C401
The C401 is a road on the north side of Lower Lough Erne. Starting on the A47 at Garvary, the road turns north west through some quiet countryside in the direction of the border. The border is soon reached as the road passes in between Tullynasiddagh Lough and Lough Vearty thus marking the end of this class III route. However the road itself continues beyond the border acquiring local classification within County Donegal.
