Our country’s infrastructure is in need of repair. Of the 600,000 bridges located over 4 million miles of roads that the government is responsible for maintaining, 1 out of 9 (or 70,000) is deemed structurally deficient. Thirty-two percent of America’s major roads are in need of extensive rehabilitation. As a result, drivers in the U.S. annually spend 5.5 billion wasted hours in traffic, resulting in costs of $120 billion in fuel and lost time. The estimated investment needed to fix this problem is $3.6 trillion by 2020. Here is how public private partnerships (PPPs) can help finance and rebuild America’s infrastructure.
