This article is about the Class III road numbered C429 maintained by DfI Roads.
For other roads numbered C429, see C429
The C429 is a short route starting on the A34 next to Mullyduff Lough. The road winds its way south east from here and reaches the County Monaghan border at Leitrim. The C class segment therefore terminates here, although the road itself continues a bit further to reach the isolated section of the N54 in between the two stretches of road which pass through County Fermanagh as the A3.
