|Route outline (key)|
The B405 connected the A4 with itself by running along the north side of Trafalgar Square in London (the A4 ran along the south side). The B405 also followed Pall Mall East to the west of the Square and Duncannon Street to the east.
The B405 seems to have been upgraded to a loop of the A4 at some time, although the short length of the road makes it difficult to determine exactly when.
The north side of Trafalgar Square is now pedestrianised but the remainder of the ex-B405 remains part of the A4.
