Council Bluffs (rather than Omaha) was designated by Abraham Lincoln as the official starting point of the transcontinental railroad which was completed in 1869. The official "Mile 0" start is at 21st Street and 9th Avenue which is now marked by a gold spike that was used for the promotion of the movie Union Pacific Council Bluffs physical connection to the Transcontinental Railroad was delayed until 1872 when the Union Pacific Missouri River Bridge opened (railroad cars had to be ferried across the Missouri River from Council Bluffs to Omaha in the early days of the Transcontinental).
