The B3405 is a short route across Pirbright Common in Surrey. The road was originally part of the A321 mainline but gained its number in the 1940s when that road was diverted to the north; it has since been downgraded to become the B3012 here.
Starting at traffic lights on the A324 in Pirbright, the road heads west out of town and then heads across Pirbright Common to join up with the B3012, which runs parallel to it, a mile or so later. The road is not currently signed on the ground – the aforementioned B3012 doing the job adequately.
An amended OpenStreetMap trace for this route awaits uploading to the SABRE Wiki.
Curiously, the 1936 5th Edition one-inch OS map suggests that the B3405 originally followed what became the A321 route, with that route staying on its original line. Whether this is a misunderstanding resulting in a misprint, or genuinely shows that the two routes swapped numbers shortly after the B3405 was created is not yet clear.
