The B3356 is a short B-road in north east Somerset. It was not originally classified in the 1922 Road Lists, but had been numbered by the late 1920s.
The road starts outside the Co-op store in the middle of Chilcompton by turning off the B3139, and heads south-east past a small industrial estate to reach the A367 at the top of the hill above Nettlebridge.
