The image shows the Rinsdorf Viaduct on the A45 motorway in North Rhine-Westphalia, Germany.
The bridge is part of a massive modernization project along the "Sauerland Line," in which many bridges are being replaced due to heavy traffic volumes.
A single section of this bridge weighs approximately 40,000 tons. In a spectacular feat of engineering, the bridge—including its piers—was laterally shifted into place.
