• Abstract:
  Phased construction allows for the replacement of a bridge while maintaining traffic flow during the construction. However, problems such as differential elevation of the phases and premature deterioration of the closure region joining the phases have been observed. Replacement of the Dodge Street Bridge over I-480 in Omaha, Nebraska, provided the opportunity to observe and closely monitor a phased constructed system. The bridge was instrumented and then monitored during construction and for an additional 5 years of in-service use. Additionally, live load testing was performed on each of the phases. Selected data and results obtained from this extensive monitoring are presented in this paper. Deformations due to temperature changes along these years were thoroughly measured and a detailed analysis of deflections was made.
