|Route outline (key)|
The B553 was originally a rural B-road in the Home Counties. It has since been upgraded to Class I status and been swallowed up as part of Greater London.
The road started on the A5 in Edgware and headed roughly eastwards. After crossing the Midland Mainline it crossed Highwood Hill, where it met the B552 and B554 in quick succession. It then crossed a short section of Hertfordshire and went through the village of Totteridge, before returning to Middlesex and ending on the A1 in Whetstone.
The entire road is now numbered A5109; the upgrade seems to have taken place in the 1940s.
