The $899 million Pennsylvania Rapid Bridge Replacement Project financial close marks a significant development for public-private partnerships in the US. It involves the largest road project in Pennsylvania history and arranged the largest Private Activity Bond financing for a P3 project in the US. The project bundles publicly owned bridge assets under a single construction contract and shares permitting risks between PennDOT and the private sector partner. It also establishes workforce requirements to benefit local communities. The success of the project's permitting process will be key as other states may pursue similar approaches.
