How America and Europe Pull Off Impossible Highway Projects. Extreme Road and Bridge Construction

How do engineers build highways where mountains collapse, the ground cannot support bridges, and roads must cross open water? This extreme engineering documentary explores massive road and bridge construction projects across the United States, Turkey, South Korea, and Europe. Watch crews clear Colorado's Interstate 70 after a mudslide, blast rock, stabilize dangerous cliffs with steel anchors and nets, drill deep foundations, transport giant bridge towers, and launch steel decks over water. See heavy machinery, earthmovers, concrete slipform pavers, and intelligent asphalt compaction in action. Discover how suspension bridges cope with earthquakes and why new pavement can look perfect while hiding weaknesses. From planning to the finished highway, every stage is a battle against terrain, weather, and time.
