Presentation Abstract
Prior to this project, no major rehabilitation had been performed on the Manhattan approach ramps to the RFK Bridge since its original construction in 1936. Due the effects of chronic deterioration, primarily at the locations of leaking expansion joints, a comprehensive rehabilitation effort of the steel portion of the structure was required. Several unique and innovative methods were used to complete this project within the congested urban environment while also maintaining traffic on these critical ramps which carry in excess of 85,000 vehicles per day. This presentation will highlight some of the design and construction challenges associated with this $70M bridge rehabilitation project, which was completed in 2017. In particular, details will be provided of the hybrid seismic isolation system that was developed to allow this 1930’s-era steel rigid-frame structure to meet modern seismic criteria.
