As the A37 follows the alignment of the Roman Fosse Way, there is a possibility that this junction is nearly 2000 years old. Lydford is certainly a historic staging point on the A37, with the Crosskeys Inn on the B3153 giving the junction its name. Curiously, however, at least one of the advance direction signs on the A37 names the junction as 'Lydford on Fosse' at the top!
Today the crossroads is controlled by traffic lights, to give traffic on the B3153 a fighting chance of getting onto or across the often busy A37. There is, perhaps, surprisingly little turning traffic, due to more direct routes for longer distance traffic, and with no room for a roundabout, traffic lights were the most viable option.
