More Potholes, Traffic Jams On The Horizon Unless Interstates Are Fixed, Report Finds

The report, “Renewing the National Commitment to the Interstate Highway System: A Foundation for the Future,” was mandated by Congress and produced by the Transportation Research Board, which is part of the National Academies of Sciences, Engineering, and Medicine.

Between 1980 and 2015, vehicle miles traveled on interstates grew by more than 160 percent, compared with a 90 percent increase on all other public roads.

Interstate highways make up 1 percent of the nation’s public roadway mileage today, but carry 25 percent of all vehicle miles traveled, including about half of all miles traveled by heavy trucks.
