When the railroad was completed between Omaha and Sacramento, rails did not completely span the continent until the year after the spike was driven. A trestle had to be built between Council Bluffs, Iowa and Omaha, Nebraska to connect to other eastern rail lines that, and a line had to extend beyond Sacramento to reach the Pa
