Renewing the National Commitment to the Interstate Highway System: A Foundation for the Future

The Interstate Highway System has conferred broad and deep benefits and has been pivotal in shaping and supporting demographic, spatial, economic, and social development in the United States for more than 50 years. The Interstate Highway System provides the main corridors for passenger and freight movement within rural and urban areas. Interstate highways must be preserved, rehabilitated, and modernized to adapt to the country’s changing demographic, economic, climatic, and technological landscape.

The Interstate Highway System’s future, despite its crucial role in the economy and society, is threatened by a persistent and growing backlog of physical and operational deficiencies and by a number of large and looming challenges.

Many Interstate highway segments are more than 50 years old, subject to much heavier traffic than anticipated, and operating well beyond their design life without having undergone major upgrades or reconstruction. These aging and heavily used segments are poorly equipped to accommodate even modest projections of future traffic growth, much less the magnitude of growth experienced over the past 50 years.

Congress asked the Transportation Research Board (TRB), a program unit of the National Academies of Sciences, Engineering, and Medicine, to form a special committee to conduct a study to inform pending and future federal investment and policy decisions concerning the Interstate System. Congress asked the committee to make recommendations on the “features, standards, capacity needs, application of technologies, and intergovernmental roles to upgrade the Interstate System” and to advise on any changes in law and resources required to further the recommended actions.

The study committee suggests a path forward to meet the growing and shifting demands of the 21st century in the report Renewing the National Commitment to the Interstate Highway System: A Foundation for the Future.

Eisenhower quote

More than any single action by the government since the end of the war, this one would change the face of America with straightaways, cloverleaf turns, bridges, and elongated parkways. Its impact on the American economy–the jobs it would produce in manufacturing and construction, the rural areas it would open up–was beyond calculation.

— President Dwight D. Einsenhower


The prospect of an aging and worn Interstate System that operates unreliably is concerning in the face of a vehicle fleet that continues to transform as the 21st century progresses and the vulnerabilities due to climate change place new demands on the country’s transportation infrastructure. Unless a commitment is made to remedy the system’s deficiencies and prepare for the challenges that lie ahead, the system risks becoming increasingly congested; far more costly to operate, maintain, and repair; and vulnerable to the effects of a changing climate and extreme weather. Looming challenges that will necessitate this commitment include the following.


Many of the Interstate pavements built in the 1950s and 1960s were designed for 20-year service lives but have now gone more than 50 years without reconstruction of their foundations, despite much higher traffic loadings than projected. While these foundations are being rebuilt, sufficient resources will be needed to preserve, restore, and rehabilitate the system’s thousands of aging bridges and other assets.

Large portions of the Interstate Highway System, especially in metropolitan areas, are chronically congested and have difficulty accommodating the demands of both local and longer distance travelers. As most of the country’s population and economic growth is forecast to occur in large metropolitan areas, the potential grows for worsening congestion unless capacity is added and more actively managed.


Although thousands of miles of high-quality highways other than Interstates connect the country’s population centers, lack of access to the Interstate System may be viewed by some smaller communities and emerging cities as detrimental to their growth and development, particularly given that the Interstate System includes the country’s main trucking corridors and links to other modes of transportation.


The Interstates are the nation’s safest highways, but they still account for more than 5,000 traffic deaths annually. As new highway and vehicle technologies are introduced, reconstruction work increases, and physical and operational measures are taken to accommodate growing traffic demand, an emphasis on ensuring safety performance will be critical.


New vehicle technologies have the potential to alter the operations and safety performance of the entire highway system, including the Interstates. The Interstate System will need to be made adaptable to changing vehicle capabilities while avoiding premature investments in assets and the introduction of standards that would hinder useful development pathways.


When much of the Interstate System was being built during the 1960s and 1970s, little was known about the threat of climate change. Transportation agencies across the country will need to make changes to how they plan, design, construct, operate, and maintain the Interstates to make them more resilient and less vulnerable to the adverse effects of climate change.


The increase of vehicle fuel economy and electric vehicles threatens a funding base that relies heavily on revenues from fuel taxes that have lagged spending needs. New funding mechanisms that are equitable and efficient and do not divert resources from other highways and transportation modes will be needed to pay for system reinvestments.


Only limited planning and budgetary preparations have been made to fix the deterioration to the Interstate System that has already occurred, much less to address the challenges that lie ahead. Recent combined state and federal capital spending on the Interstates has been about $20–$25 billion per year. The estimates in this study suggest this level of spending is too low and that $45–$70 billion annually over the next 20 years will be needed to undertake the long-deferred rebuilding of pavements and bridges and to accommodate and manage growing user demand. This estimated investment is incomplete because it omits the spending that will be required to meet other challenges such as boosting the system’s resilience and expanding its geographic coverage. While these investment needs could not be estimated even roughly for this study, they are certain to require billions, and perhaps tens of billions, in additional annual spending.


…what makes today’s investment choices so critical is that much of the Interstate System is already past due for major reconstruction and modernization…

—Committee for a Study of the Future Interstate Highway System


The original Interstate Highway Construction Program was underpinned by a long-term, collaborative commitment among the states and the federal government. A comparable partnership is needed to renew and modernize the system and ensure that it is resilient and responsive to the changing demands of users.


Congress should legislate an Interstate Highway System Renewal and Modernization Program (RAMP). This program should focus on reconstructing deteriorated pavements, including their foundations, and bridge infrastructure; adding physical capacity and operations and demand management capabilities (e.g., tolling) where needed; and increasing the system’s resilience.

The RAMP should be modeled after the Interstate Highway System Construction Program by reinforcing the traditional program partnership in which the federal government provides leadership in establishing the national vision for the overall system, the bulk of the needed funding, and overall standards, while states prioritize and execute projects in their continued role as owners, builders, operators, and maintainers of the system. The federal share of project spending should be comparable to the 90 percent share of the original Interstate Highway System Construction Program.

Congress should, as a near-term step, (1) increase the federal fuel tax to a level commensurate with the federal share of the required RAMP investment, and (2) adjust the tax as needed to account for inflation and changes in vehicle fuel economy.


To ensure that the federal government’s long-term commitment to RAMP is not threatened by declining motor fuel tax revenues as the vehicle fleet and its energy sources evolve, Congress should prepare for the need to employ new federal and state funding mechanisms, such as the imposition of tolls or per-mile charges on users of the Interstate Highway System.

To provide states and metropolitan areas with more options for raising revenue for their share of RAMP investments and for managing the traffic demand on and operations of Interstate segments that offer limited opportunity for physical expansion, Congress should lift the ban on tolling of existing general-purpose Interstate highways. As a condition for imposing those tolls, states should be required to assess their impact on current users and offer alternative mobility options for those users significantly and disproportionately harmed by the tolls.

A “rightsizing” component of RAMP should address current and emerging demands to extend the Interstate System’s length and scope of coverage and to remediate economic, social, and environmental disruptions caused by highway segments that communities find overly intrusive and are not deemed vital to network traffic. Congress should direct the U.S. Department of Transportation and the Federal Highway Administration to develop criteria for such system rightsizing using a consultative process that involves states, local jurisdictions, highway users, and the general public.

A Blueprint for Action

Recommendation 1. Congress should legislate an Interstate Highway System Renewal and Modernization Program (RAMP). This program, presumed to be pursued without sacrificing normal ongoing system maintenance and repair, should focus on reconstructing deteriorated pavement, including their foundations, and bridge infrastructure; adding physical capacity and traffic demand and operations management capabilities where needed; and increasing the system’s resilience.

Recommendation 2. A “rightsizing” component of RAMP should address current and emerging demands to extend the Interstate System’s length and scope of coverage, and to remediate economic, social, and environmental disruption caused by highway segments that communities find overly intrusive and are not deemed vital to network and intermodal traffic. Congress should direct the U.S. Department of Transportation (U.S. DOT) and the Federal Highway Administration (FHWA) to develop criteria for such system rightsizing using a consultative process that involves states, local jurisdictions, highway users, and the general public.

Recommendation 3. To better ascertain the spending levels required for RAMP investments, Congress should direct U.S. DOT and FHWA to join with the states to assess the foundational integrity of the system’s pavements and bridges, and identify where full reconstruction is needed based on accepted life-cycle cost principles.

Recommendation 4. To pay for RAMP investments, Congress should, as a near-term step, (1) increase the federal motor fuel tax as needed to a level commensurate with the federal share of the required investment, and (2) adjust the tax as needed to account for inflation and changes in vehicle fuel economy.

Recommendation 5. To provide states and metropolitan areas with more options for raising revenue for their share of RAMP investments and for managing the operations of Interstate segments that offer limited opportunity for physical expansion, Congress should lift the ban on tolling of existing general-purpose Interstate highways. As a condition for imposing those tolls, states should be required to assess their impact on current users and offer alternative mobility options for those users significantly and disproportionately harmed by the tolls.

Recommendation 6. To ensure that the federal government’s long-term commitment to RAMP is not threatened by declining fuel tax revenues as the vehicle fleet and its energy sources evolve, Congress should prepare for the need to employ new federal and state funding mechanisms, such as the imposition of tolls or per-mile charges on users of the Interstate Highway System.

Recommendation 7. To support renewal and modernization investment decisions, Congress should direct, and provide sufficient funding for, U.S. DOT and FHWA to develop modeling tools and databases that track the full condition of Interstate assets, including interchanges, and their reconstruction history; can be used to assess transportation options that can supplement or substitute for additions to Interstate highway capacity; allow for the monitoring and modeling of network-level traffic flows on the Interstate Highway System; and further federal and state understanding of the demand for long-distance and interregional passenger and freight travel by highway and other modes. Because these recommended activities are important for guiding reinvestment in the Interstate System, careful consideration should be given to carrying them out in an effective and efficient manner. Recommendation 8. Congress should direct U.S. DOT and FHWA, working with states, industry, and independent technical experts, to start planning the transition to more automated and connected vehicle operations. This effort should entail performing the needed research and updates to Interstate Highway System requirements and standards so as to ensure that basic intelligent transportation system (ITS) instrumentation is adopted on a consistent and system-wide basis, and that the uniformity and other attributes of pavement markings, interchange design, and the like are capable of facilitating eventual Interstate use by connected and automated vehicles. An emphasis should be placed on ensuring that renewal and modernization projects give full consideration to safety impacts, including the deployment of advanced design and operational features that have demonstrated effectiveness in improving safety, and that cybersecurity protections are incorporated into the designs and upgrades of the Interstate highways and the vehicles that use them.

Recommendation 9. Expanding upon earlier legislative directives (e.g., the Moving Ahead for Progress in the 21st Century [MAP-21] Act and the Fixing America’s Surface Transportation [FAST] Act) for transportation agencies to consider resilience in long-term planning, Congress should direct U.S. DOT and FHWA to substantiate that state Interstate highway renewal and modernization projects have fully taken into account the need for resilience. To support these efforts, U.S. DOT and FHWA should be directed to assess the vulnerability of the Interstate Highway System to the effects of climate change and extreme weather; develop standards, in conjunction with states, for incorporating cost-effective resilience enhancements into projects; and develop and maintain a database of cost-effective practices and resilience strategies employed by state highway and other transportation agencies, including any funding mechanisms dedicated to support resilience planning and implementation.

Recommendation 10. Congress should direct U.S. DOT and FHWA to ascertain the Interstate Highway System’s contribution to the country’s emission of greenhouse gases and recommend options for reducing this contribution in conjunction with reductions in other emissions of pollutants. The effort should build on past initiatives, such as legislation requiring states to consider the emissions impacts of capacity expansion and demand-management options, and legislation mandating a federal program to examine the siting of facilities that support alternative-fueled vehicles, such as electric vehicle charging stations located on Interstate highway corridors.



Implementation of the above recommendations, together with several other complementary recommendations called for in the report, would represent a fundamental shift away from a federal policy that has lost focus on the Interstate System and the commitment to funding it adequately. These actions would restore the system’s premier status within the nation’s highway program in a manner that is aggressive and ambitious, although by no means novel. Taking these actions would

(1) rekindle a tried-and-true federal–state partnership;

(2) reinforce the system’s long-standing reliance on user fees to provide a fair, adequate, and reliable source of funding; and

(3) reassert the forward-looking vision that was instrumental to the genesis of this crucial national asset more than a half-century ago.

At that time, the nation’s leaders endorsed a modern highway system that would confer large and lasting societal and economic benefits, a vision whose realization required a strong and continuing national commitment. Today, the nation is experiencing, and can anticipate, new expectations for system performance, condition, and use. Meeting those expectations will require the same forward-looking outlook and commitment that informed the system’s creation—a rededication to that original vision that reshapes and re-equips the system to serve generations to come.

The future of the U.S. Interstate Highway System is threatened by a persistent and growing backlog of structural and operational deficiencies and by various looming challenges, such as the progress of automated vehicles, developments in electric vehicles, and vulnerabilities due to climate change. Unless a commitment is made to remedy the system's deficiencies and prepare for these oncoming challenges, there is a real risk that the nation's interstates will become increasingly unreliable and congested, far more costly to maintain, less safe, incompatible with evolving technology, and vulnerable to the effects of extreme weather, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine. The report calls for a 20-year blueprint for action, which includes creating an Interstate Highway System Renewal and Modernization Program, increasing the federal fuel tax to help pay for it, and allowing tolls and per-mile-charges on more interstate routes.
