Transportation funding is in desperate need of an overhaul, according to a report from the Pew Charitable Trusts. The numbers—which reach into the billions of dollars—are frightening. Budget cuts, population shifts, and growth, are impacting infrastructure, and the federal government isn’t solely to blame. “Intergovernmental Challenges in Surface Transportation examines the role that each level of government plays in paying for highway and transit infrastructure, the key problems facing this multilayered system of funding, and their causes,” states a press release on ForConstructionPros.com. The Pew report also identifies central principles that policymakers need to consider as they weigh options and consider solutions.
