Scope of Work:
ECCO III was designated by NYSDOT as the best value Design-Builder for this Project, which aims to improve the resiliency of two bridge crossings, one carrying Route 209 over Rochester Creek (BIN 1040750) located in the Town of Rochester, and the other carrying Route 28 over Esopus Creek (BIN 1019700) located in the Town of Shandaken. The two structures will be completely removed and replaced with new bridges that have been designed to meet the hydraulic requirements at each site, while maintaining compatibility with the potential future Wild, Scenic and Recreational River designation of the adjacent Rondout (Route 209) and Esopus (Route 28) Creeks.
At the Route 209 site, the bridge and approach roadways will be reconstructed at a higher elevation to minimize flooding, and will be longer than the existing structure.At the Route 28 site, the new bridge will: reduce the opportunity for the collection of debris with a reduction in the number of piers; minimize the undermining of any structural elements by scour; and accommodate the meandering nature of the crossing streams.
The bridge replacement work at each bridge includes new foundations, substructures, superstructures, approach slabs, and highway approaches within the existing ROW. The work also includes highway construction and reconstruction, work zone traffic control (WZTC), coordination with and/or preservation of existing utilities, remediation and disposal of asbestos containing material, fabrication and installing of new guide rail and bridge rail, and coordination of public involvement activities.
