History
The bridge was constructed from 1911-1915.[2] and was opened by Mayor Joseph G. Armstrong on August 8, 1915.[3] It was closed to traffic on October 17, 1969 when its successor, the Fort Duquesne Bridge (located closer to the Roberto Clemente Bridge) opened that same day. It was demolished in the autumn of 1970. Explosives were used to drop the south side span into the river at 18:42 on September 29, 1970.[4] The original attempt 11 hours earlier was unsuccessful when five of the eight charges failed to detonate. Demolition was subcontracted to Controlled Demolition by Dravos and was overseen by John. D Loizeaux.
