|Route outline (key)|
The C402 is another route which is in two distinct parts. The longer section is the C402-020 which starts on the A970 at Swinister and heads west to meet the C401-100 at Assater. There is no apparent logic as to why these two pieces of road don't share a number.
The shorter part of the C402 is the C402-080 which lies many miles to the east and forms a very short link from the B9078 west to the former post office at Hoohivda, at the head of Hamna Voe.
