|Route outline (key)|
The B557 was a medium-length B-road in the Home Counties.
It started on the A5 between Fenny Stratford and Little Brickhill. It headed north then east through Bow Brickhill and then on to Woburn Sands, where there was a short multiplex along the A506 (later A50).
The B557 survived the arrival of the M1 in the 1950s but disappeared in stages from then on. The section north of the M1 became the A5140 and later the A421; it has now been bypassed with the old road numbered C94 (which is technically two different classified roads, the C94 (Central Bedfordshire) and C94 (Bedford)). The section within the Bedford bypass has regained Class II status, being numbered B531. The section south of the motorway survived longer but was declassified with the growth of nearby Milton Keynes.
