At this point, the Junior League of Syracuse took notice and was shocked to find drawings at the DPW showing Interstate 81 going right over the Weighlock Building and Syracuse City Hall. The Junior League, and others went into high lobbying gear, with intense letter writing and phone calls to Albany legislators and the Chairman of the Onondaga County Board of Supervisors. The Junior League persuaded the Board of Supervisors to accept the Weighlock Building on behalf of Onondaga County. The transfer from the State was authorized by the legislature and signed into law by Governor Rockefeller.
The instrument of conveyance from New York State provided that the property must be used for a “public canal museum.” Consequently, at the request of the County, the original Board of Trustees started out to create such a museum. Work began in earnest, mostly with volunteers, to clean, paint and revitalize the interior of the building, while County employees made a significant contribution to the renovation of the building. In September 1962, the Board of Regents granted a “provisional charter” and the formal opening in October was greeted by large, enthusiastic crowds. The “absolute charter” of the Museum was issued by the Board of Regents on March 29, 1968.
