Federal funding through the Bipartisan Infrastructure Law, with over $100M specifically allocated to public-private partnerships (P3s), and the Inflation Reduction Act, combined with historic levels of private investment into infrastructure and energy assets, services, and technologies, make this an exciting time for our sector. Furthermore, incentives for state and private entities to realize new and lasting infrastructure exist through the Transportation Infrastructure Finance and Innovation Act (TIFIA), which allows for 49% of projects to be funded with low-interest rate loans, and P3 funding for clean energy and broadband projects.
However, delivering such solutions is no easy task, especially given the desire to integrate new technologies into our energy, mobility, and communications infrastructure (e.g., renewable power, green hydrogen, electric vehicles) and create equitable digital access (e.g., rural broadband), and the inherent complexity of these systems.
We are seeing a growing desire to utilize P3s given the complexity and sheer volume of infrastructure to be delivered and the need to partner with the private sector effectively to integrate and deploy new technologies. Recognizing the need for innovation in infrastructure delivery, alternative delivery models enable effective partnerships between the public sector, private capital, and technology & service providers to maximize public benefit with available funding.
For the next installment of the series Bridging the Gap: Propelling America’s Public Infrastructure Forward, we’ll review best practices in structuring and executing alternative delivery models, how some states have experienced success, and what leaders can do to successfully shape and implement innovative ways of delivering infrastructure.

P3s have been used to deliver infrastructure in the U.S. for decades, delivering over 150+ projects worth over $130B since 2012 in roads, transit, airports, water, and more asset classes. The U.S. is the largest P3 market in the world, and some of the nation’s most successful infrastructure projects in recent years have been delivered through P3s. For example, the new LaGuardia Airport project utilized innovative design and construction delivery to minimize disruption during construction and deliver a vastly improved travel experience.

P3s, however, must be thoughtfully designed and managed as challenges often arise in aligning the public and private sectors. For instance, due to these conflicts, a Midwestern state’s airport project was canceled after months of private sector engagement with a highly qualified consortia offering to finance and build, despite potentially injecting millions of dollars into the local economy and creating thousands of jobs.
In instances where P3s succeed, states and localities can create lasting impacts. Prince George’s County Public Schools (PGCPS) in Maryland used a P3 model with a team of private firms to design, finance, construct, and maintain 6 new public schools. In July 2023, this P3 is anticipated to deliver in 4 years what traditional execution models would deliver in 12 years. Furthermore, the 30-year maintenance contract is expected to save up to $180M in deferred O&M costs by transferring the risk of construction and operations to the private sector, converting variable operation and maintenance (O&M) costs into fixed payments. In another Mid-Atlantic state, P3 projects experienced on-time or earlier completion and only 1-3% cost overruns compared to 15+% for traditional delivery. With over $550B in net-new federal infrastructure funding from the federal Infrastructure Investment and Jobs Act, P3s, through minimizing time and cost overruns, have the potential to save up to $83B (approximately 15% saving on the $550B in net-new infrastructure projects) in funding that can then be deployed for other much-needed infrastructure initiatives.
Delivering infrastructure using alternative delivery models is complex, and challenges include:
States can develop a P3 approach that creatively leverages the best of both the public and private sectors. We recommend the following:
P3s are long-term projects that require close collaboration between the public and private sectors. Accordingly, the P3 model does not fit all infrastructure projects, and states should only consider those where the incentives between public and private are aligned and where the government may not be best positioned to deliver due to either capacity, funding, knowledge, or experience constraints. Considerations that may influence a project’s P3 viability include the benefits for private involvement, clear pathways to optimize private efficiency and effectiveness, a healthy market of competitive providers with sufficient engagement, limitations of public sector capacity, budget and/or ability to deliver and analysis of key trade-offs to balance.
Recommended actions for states:
P3 success starts with appropriately structuring the risks and rewards of a project between the public and private sectors. Various models exist within P3 from public ownership with private delivery to public-private co-ownership to private-owned delivery of public resources. States must balance their specific needs against revenue, operations, and risk considerations, thereby setting up projects for success while protecting governments from “giving away the store.”
Recommended actions for states:

Alternative delivery requires a different approach compared to traditional delivery models. We recommend establishing an infrastructure organization (given a large enough number of P3 projects to support) to act as a P3 center of excellence for state, county, and local teams. This organization which can take the form of a council, agency, or department, can provide resources for funding, partner selection, bid evaluation, long-term monitoring, and more. Additionally, the organization can support P3 planners in obtaining federal funding and support, such as through the Transportation Infrastructure Finance and Innovation Act (TIFIA) which provides loans, loan guarantees, and other forms of credit assistance to help finance projects.
Recommended actions for states:
The Gateway Arch Park in Missouri is a prime example of a successful P3 that aimed to deliver a complete redesign for the Gateway Arch grounds and connect its public spaces to those of Downtown St. Louis. Coordinating across stakeholders, effectively sharing risks, and long-term collaboration, the P3 team completed the project on time and on budget while ensuring full visitor access to the Gateway Arch over the entire duration of construction. Public funding totaled $159M from federal, state, and local sources, while the Gateway Arch Park Foundation raised an additional $221M from the private sector, without which the project would have stalled indefinitely. Through a clear vision, the Gateway Arch Park exemplifies how P3s can revitalize public spaces, boost tourism, and preserve cultural heritage.

P3s offer an innovative model to attract investment and enable the completion of more infrastructure projects. Additionally, they can improve incentives to optimize long-term lifecycle costs without sacrificing on-time and on-budget delivery. Through thoughtful contract structuring, P3s can also create predictability in long-run liabilities and free up public cash flow to fund other critical initiatives. Together, the public and private sectors can transform our infrastructure landscape, foster economic growth, and improve the quality of life for all.
