The Tappan Zee Bridge & public private partnerships
The reconstruction of the Tappan Zee Bridge, one of the largest public works projects in the nation, may establish a new model for public private partnerships (PPPs). The collaboration between the public and private sector has been common in Europe for decades and has been used increasingly for roads, but never for a project of this magnitude. The combination of a PPP approach, a design-build contract and creative financing may ultimately have a broader application statewide. It has been estimated that of the more than 17,000 bridges in New York State, 6,650 may be structurally deficient. Once a suitable PPP model is established based upon a design-build concept (preparation of design and construction under a single contract), the model may be adapted to other circumstances. The open issue is the nature of the financing for the reconstruction. To assist the administration in examining financing options, two entities, Jeffrey Parker and Associates and Acacia Consulting, have tentatively been selected to determine how best to finance the reconstruction for the project.
