Bergmann Associates was retained by CSXT to serve as the owner's representative overseeing the demolition of this National Register Eligible, 92 year old, double track, through truss swing bridge. The demolition consisted of full removal of the 304 ft long through truss and control house, timber starkwaters (end rests), timber fender system and pilings, center pivot pier and pilings and contaminated sediment dredging and disposal.
Located in the middle of the Genesee River at the confluence with Lake Ontario, the bridge site features significant commercial and recreational boat traffic, adjacent facilities (marinas, public launch and businesses) and is a sensitive fish and marine habitat. These, coupled with the bridge's historic significance, required extensive environmental coordination with numerous local, state and federal agencies including; the USACE, NYSDEC, Landmark Society, Department of State, U.S. Coast Guard, NYSOPRHP, National Advisory Council on Historic Preservation, City of Rochester and the Town of Irondequoit as well as local rail and preservation groups. During the permitting and historic mitigation process, Bergmann served as the technical structural advisor to CSX and their permitting and legal consultants providing cost estimates, technical narratives, drawings and other advice as needed.
