The B3346 was a short road to the east of Weston-super-Mare. The number came about in the mid-1920s when the A370, which originally ran along Worle High Street, was moved onto the newly built New Bristol Road and the vacated section of road was given Class II status.
The B3346 number was seemingly still in use in 1946, but subsequent maps whilst showing it as a B road generally do not label it. However, large scale OS sheets, and the 1960s 1:25,000 regularly give the number B3146, a duplicate from Dorset, and presumed to be a misprint. To further confuse matters, the B3440 number seems to have also been applied to this route in the later 1970s or early 1980s, and survived until the early 21st century, when it was belatedly declassified after being relegated to a spur with the opening of the new dual carriageway Somerset Avenue.
As the B3440 number is also used by Devon (for part of the former B3391), it raises the question as to why the B3346 number was dropped, and when exactly the number was changed. The confusion with the B3146 may have precipitated the change.
