The C402 is a C shaped route in north Fermanagh. It starts on the A35 at Letterkern and heads north west, almost immediately crossing the C403 as it does so. After crossing the Brannagh River the road turns more to the west and crosses the C450. The road then swings round to the north and comes to a TOTSO from which it heads north east. After a short distance the road ends on the U class Formil Road.
