Story
On this episode of Modern Marvels we'll construct, and deconstruct, the roundabout ribbons that comprise the world's Superhighways. Our road trip starts in Houston, Texas where a multi-billion dollar expansion project is widening a stretch of superhighway to a spacious 20 lanes. Then we're off to China's 28,000-mile National Trunk Highway System.
