InfrastructureU.S. Interstate highways need overhaul, requiring government’s commitment, funding
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.
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.
“The interstates have long been the backbone of our country’s transportation system, but most of them have exceeded their design lives and in many places are worn and overused,” said Norman Augustine, former chairman and CEO of Lockheed Martin Corp. and chair of the committee that wrote the report. “These aging interstates are highly congested oftentimes and in need of reconstruction. Furthermore, technological advances are offering new opportunities, but they may also undermine a principal source of income for the interstates, namely the tax on fuel. We recommend a course of action that is aggressive and ambitious, but by no means novel. Essentially, we need a reinvigoration of the federal and state partnership that produced the Interstate Highway System in the first place.”
