|Route outline (key)|
The B3057 was allocated to a new-build road in the 1980s, serving Badger Farm estate southwest of Winchester. The road started on the A333 where that road turned from St Cross Road to Five Bridges Road, a road now closed to through traffic. After a brief trip south along the pre-bypass A33 the road bore right onto the new-build Badger Farm Road, ending after a couple of miles on the A31.
When the M3 was completed over Twyford Down, all remaining A roads in Winchester were downgraded, and so the Badger Farm Road became part of a rerouted A3090 and St Cross Road became part of the B3335. Thus, the fourth and final incarnation of the B3057 was no more.
