|Route outline (key)|
This road contained the southern section of Queen's Drive, now the Liverpool ring road. It is therefore not surprising that it was soon upgraded to Class I status.
The ex-B5172 is now the southern half of the A5058. Although to begin with that road followed the B5172 exactly, in more recent years the original southern end of the B5172 has been declassified, with the A5058 now running along Victoria Road rather than Aigburth Vale.
