| Abstract: |
Six bridge projects in Colorado are complete or are currently being constructed using curved, precast concrete girders. In all cases, the girders were spliced and in most applications, post- tensioned to accommodate spans up to 265’. These projects were developed to utilize plant manufactured precast concrete girders using variations of standard Colorado DOT cross sections. Of the six projects, two including the Ramp K and Ramp H Flyover Bridges, have been completed and are currently in service. The remaining projects have been designed and are at varying stages construction. The Ramp K Bridge will be featured as case study to discuss the technical and constructability issues that are inherent in this type of construction. Other projects, currently under construction, will also be discussed. These design and construction of these projects faced many challenges in difficult urban site conditions. Unique solutions for spliced girder technology that were developed during both design and construction will be discussed. |
