The 2,000-foot bridge was constructed without a single drawing
A Norwegian bridge was engineered using entirely 3D models, an emerging approach that saves both time and money.
Soaring above a forest outside of Oslo, Randselva Bridge is remarkably unremarkable. A straightforward viaduct for cars and trucks, the gently curving bridge straddles a river, a valley, a rail line and foothills. The bridge stretches 634 meters, or 2,080 feet, and stands 180 feet above the ground at its highest point. Like many highway projects around the world, it has been engineered to span great distances and stand strong—feats that have become so normal they’re expected as the status quo. But unlike most large-scale building projects, this bridge has been designed and constructed without any drawings.
