"...an enormous, groundbreaking project: nearly 20 kilometers (12.5 miles) long, 40 meters (130 feet) wide, nearly 10 meters high -- and expected to cost at least €5.5 billion ($7.2 billion). Four tubes are planned: two for the highway, each with two lanes, and two for the railway, each with one track. The tunnel would consist of huge concrete elements assembled on land and lowered by boats into a colossal trench on the Baltic seafloor. It would be one of the longest immersed tunnels ever built."
