A crisis is brewing in the American interstate highway system -- traffic volumes are rapidly increasing and roads are falling apart faster than they can be fixed. In Man-Made: Super Roads, NGC visits highway construction sites across the country to explore how machinery, technology and engineering keep our interstates flowing smoothly. Travel down some of the nation's busiest major highways as construction workers battle extreme temperatures to fix the crumbling roads and poor traffic design. Produced by Powderhouse Productions
