PCI eLearning Course T225: Case Studies and Emerging Developments of Full-Depth Precast Concrete Deck Panels-Deck Widening and Replacement of Woodrow Wilson Memorial Bridge

Deck Widening and Replacement of Woodrow Wilson Memorial Bridge

Pdf Summary

The Woodrow Wilson Memorial Bridge on I-95, located south of Washington, D.C., was constructed between 1959 and 1962. By 1977, the bridge was showing signs of deterioration, and peak daily traffic exceeded 110,000 vehicles. The Maryland State Highway Administration contracted with Greiner Engineering Sciences to design and conduct studies for the replacement of the bridge deck while maintaining traffic flow. The final design included the use of prefabricated lightweight concrete deck panels and polymer concrete and mortar for certain details. The project also involved the installation of temporary work platforms and open grid deck panels to facilitate construction. Construction operations involved removing the original deck, setting the precast concrete panels, and performing post-tensioning and grouting operations. The entire deck replacement was completed within 350 calendar days, ahead of schedule. The project was recognized with the Special Jury Award in the 1983 PCI Awards Program and the 1984 Grand Conceptor Award from the American Consulting Engineers Council.
