Located in Nevada County, in Califnornia, USA, Donner Summit Bridge is one of the most spectacular bridges in the world.
Located in the northern Sierra Nevada, the concrete arch style bridge is dedicated to the pioneers who blazed the overland trail through these mountains. Considered one of the most beautiful bridges in California, it has both a curve and a gradual grade (the first of its kind to have both). The bridge carries the asphalted Donner Pass Road.
The bridge was built by the US Bureau of Public Roads and the California Highway Commission in 1926 at a full 241 feet long. A full restoration was completed in 1993. The bridge, also called Rainbow Bridge, sits at 2.108m (6916ft) above the sea level.
