The B5394 is a short B-road in Frodsham, Cheshire. Owing to its short length its history is not fully known. The route was originally unclassified and it had definitely gained Class II status by the mid-1940s.
The road allows traffic travelling from the A56 to the B5152 to bypass Frodsham town centre. It is called Fluin Lane throughout its length and has a 30 mph speed limit.
Some recent maps have shown the B5394 as the B5439; however, this road number exists in Thornton-Cleveleys, Lancashire, whilst earlier maps do show the B5394 existing in Frodsham.
