Now-demolished reinforced concrete parabolic arch bridge carrying Alresford Road over the Winchester Bypass
M3 through Winchester
M3 passes under B3420 When this road was the old Winchester By-pass there was a much more elegant bridge, built in the late 1930's at the same time as the 2 lane concrete road. The bridge achieved notoriety during the ensuing war when the pilot of a single engined fighter aircraft enjoyed the view you have here by flying under the Alresford Road (B3404). The epithet 'Spitfire Bridge' was henceforth applied to the old bridge, even though there is some doubt as to the aircraft type involved.
