|Route outline (key)|
The B300 is a short road on the south bank of the Thames.
The B300 crosses the A300 at a staggered junction partly underneath the railway line west of London Bridge station. Now two-way, it continues west to meet the A201 by Southwark tube station. This was the original eastern end of the B300.
An amended OpenStreetMap trace for this route awaits uploading to the SABRE Wiki.
