Renewing & Modernizing the Future U.S. Interstate Highway System – New Report Dec. 6

Since its creation more than 60 years ago, the U.S. Interstate Highway System has been pivotal in shaping and supporting the country’s demographic, spatial, economic, and social development.  Between 1980 and 2015, vehicle-miles traveled on the system grew by more than 160 percent, compared with a 90 percent increase on all other public roads.  Currently, interstate highways accommodate one-quarter of all miles traveled by cars, light trucks, and SUVs and 40 percent of all miles traveled by trucks. 

A new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine evaluates the current state of the Interstate Highway System, identifies future challenges and concerns, and recommends options and funding opportunities to improve weaknesses and modernize its infrastructure.

The report will be released at a public briefing event beginning at 11 a.m. EST Thursday, Dec. 6, in Washington, D.C., where the chair and members of the committee will discuss the findings of the report and answer audience questions.  Those who cannot attend in person can watch a live webcast of the briefing here.
