The Bletchley Flyover is a railway viaduct that crosses the West Coast Main Line (WCML) just south of Bletchley railway station in Milton Keynes, England. It was originally a reinforced concrete railway viaduct that carried the former Varsity line between Oxford and Cambridge from 1959 until its closure in 1968. The flyover was retained, but largely unused until 2021, when the East West Rail Alliance demolished then rebuilt the structure. It reopened for engineering use in early 2022.
