This presentation will cover a brief history of the Henry Hudson Bridge and the recent reconstruction of a major section of the original bridge: Project HH-88B/13A. From a design and construction perspective, the reconstruction project posed many challenges due to the multiple layers of the bridge and the limited footprint upon which the work was carried out. The successful completion of the project extended the service life of the bridge and greatly enhanced traffic safety, flow, and sight distance. The new construction has ensured a safe and reliable link to Manhattan from the north, with a new structure that meets modern geometrics and seismic standards. Major work items included the removal of intermediate columns supporting the upper-level deck, the complete replacement of seven spans of the upper-level roadway and eight spans of the lower-level roadway, including roadway, steel framing, columns and deep foundations, retaining walls, and abutment reconstruction, pavement and drainage replacement, and roadway lighting replacement.
