Deep dives into extreme civil engineering, megaprojects and the physics behind bridges, tunnels, underground stations and energy infrastructure — from the Grand Structures YouTube channel.
How Israel Found a 1-Mile Tunnel 270 Feet Inside Solid Rock Directly beneath a quiet mountain village in northern Israel, 270 feet (80 meters) underground, a hidden corridor…
Saudi Arabia’s 1,200-km East-West pipeline now moves up to 7 million barrels a day to the Red Sea, bypassing Hormuz. How it works and its limits.
How Israel’s Tel Aviv–Jerusalem railway crosses the Arazim Valley on Bridge 10, a viaduct up to 310 feet high built between two mountain tunnels. Watch the documentary.
Jerusalem’s Yitzhak Navon station sits 260 feet (80 m) underground, one of the deepest heavy-rail stations on Earth. How and why engineers carved it out of solid rock.
Tel Aviv’s Red Line stations sit 100 feet deep in wet coastal sand. How slurry walls, tension piles and jet grouting stop them from floating up like a bottle.
Israel’s Gilboa pumped-storage plant stores electricity by moving water between two reservoirs 500 m apart, delivering 300 MW to the grid. How the mountain battery works.
How can anyone map a bunker buried under 80 meters of rock? Seismic sensing, radar satellites, gravity measurements and heat signatures — the physics explained.
