|Route outline (key)|
The B4454 number appeared in some online mapping before 2009 (notably Google Maps) as Alfred Squire Road and March End Road, in Wednesfield, Wolverhampton. This is almost certainly a mapping error for B4484, which formerly ran along the eastern part of that route, though it is possible that the road held this number for a short time.
March End Road is now part of the Class III Road U99, whilst Alfred Squire Road is seemingly unclassified.
