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.
