Descrição: The entire roadway of the approach viaduct was replaced with minimal disruption to traffic. The design, tolerant of errors and maximizing prefabrication, achieved quick replacement. Foundations were rotated by inserting hinges and cutting through the mass concrete piers. Plans were prepared for replacing the suspended structure of the main spans without disrupting Monday to Friday traffic. Design criteria are given for limit states of old steel, buckling of rivetted compression members, fatigue resistance of welded tubular construction, and temporary obstructions in the roadway. The effects of turbulence on aerodynamic stability led to the use of solid guard rails. Problems associated with progressive replacement of the suspended structure are discussed. The importance of public information during reconstruction is emphasized.
