Revisiting the 1875 Northern Pacific Bridge Collapse at Brainerd, Minnesota

Описание к видео Revisiting the 1875 Northern Pacific Bridge Collapse at Brainerd, Minnesota

When the Northern Pacific Railroad bridge at Brainerd, Minnesota, collapsed on July 27, 1875, it left a huge gap in the transcontinental railroad line. Goods and other supplies quickly piled up on either side of the Mississippi River. To get the railroad line back up quickly, railroad officials built a temporary pile bridge to fill the gap in the line, and rebuilt a new bridge to replace the collapsed one. The temporary bridge took 15 days to build, while the replacement bridge took about eight months to complete. Take a closer look at the process involved in replacing the collapsed bridge. Learn about what may have been the cause of the initial failure. See the latest engineering features and hear about the individuals responsible for the reconstruction.
