WHY IT MATTERS: Infrastructure

JEFFERSON CITY, Mo. — THE ISSUE: The U.S. interstate highway system, celebrating its 60th birthday this year, is showing its age. Many roads and bridges are in need of repair or expansion. Similar problems exist for public drinking and wastewater systems, dams and levees, airports, railroads and mass transit systems. Politicians generally agree the nation’s infrastructure is in need of improvement. Deciding how to pay for it and which projects should take priority is more difficult.
