Interruptions in the building material supply chain may slow down construction of the new Humane Society of Southern Wisconsin, but officials are moving forward with a great deal of optimism. A crowd of well wishers, board members, volunteers, donors, and staff gathered together Monday morning for a groundbreaking at the new almost 45 acre site south of Janesville. Officials say fundraising is well beyond the half-way point to complete the more than 16-thousand square foot facility on County Highway G. The doors are expected to open sometime in March.
