Robert Poole, director of transportation policy at Reason Foundation: "Across the country, needed infrastructure projects are bogged down by politics and a system that prioritizes pork over mobility. But we need a 21st-century transportation system and here are several ways to get there: Rethink the federal role in transportation to focus federal gas-tax money on highway projects that deliver the largest benefits to mobility and congestion relief. Taxpayers have lost confidence in transportation spending because they’ve seen too many 'Bridges to Nowhere' built while their own commutes get longer."
